Show Me the Color SHOW ME THE COLOR From: A simple guide to understanding color by Judit Ruiz Ricart How Color Impacts Photography by Spencer Cox 8 great tips for using Color in Photography by Heather Joy Milne Alterspark.com - Color Psychology and Theory COLOR THEORY The Spectrum • All the colors we see are between 400nm (red) and 700 nm (violet) on the electromagnetic spectrum. • Based on how the human eye works they are split into three different orders: primary, secondary, and tertiary. While these categories are not clear-cut, they can serve as general guidelines on how to use color in your photos. • The more pure a color is - that is, the closer it is to a primary color - the more attention it will draw to itself on the image. • Primary • You might remember from basic biology class that humans have three types of color receptor cones in their eyes, each of them sensitive to different wavelengths corresponding to blue, green, and red colors. These three colors are known as the primary RGB colors, and all other colors in the spectrum come from combining at least two of them. • Secondary • Secondary colors are those that require the visual stimulation of two different receptor cones. For example, seeing the color yellow requires a balanced amount of red and green light. • Tertiary • Also known as intermediate colors, tertiary colors are those resulting from the mix of a fully saturated primary color with another half-saturated primary color, and none of the third primary color. You can also get them by combining a primary color with a secondary color. • How you see a color is also greatly impacted by the colors adjacent to it, which is why many art galleries have white walls. COLOR SCHEMES • Creating balanced color combinations (schemes) is critical to using color effectively. The three most common types of color schemes are complementary, analogous, and monochrome. • Complementary colors • Complementary colors are those found in polar opposite sides of the color wheel. The juxtaposition of the two hues results in a bold, vivid contrast. Colors that are complementary inherently balance one another. • Analogous colors • Analogous color schemes are those that use adjacent hues on the color wheel. They’re usually based on a primary color that serves as the connection between all of them, but in some cases the dominant hue might be a secondary color. The lack of strong contrast between colors results in images that feel balanced and calming. • Analogous color schemes are often found in nature, which makes them especially popular in the fields of nature and landscape photography. Think of the rich oranges and reds of a forest in fall, or the blue and green tones of the ocean. • Monochrome • Monochrome color schemes refer to any composition that uses only a single hue, with variations of its tones and shades. This type of image can be really impactful, as the subject tends to dominate the shot while still feeling in sync with its surroundings. Original COLOR VARIABLES Hue • Each color has a wide range of tones and shades, which transform a basic color wheel into the complete palette of the 10 million colors humans can see, determined by the color variables of hue, saturation, and luminance respectively. These Saturation variables are commonly referred to as HSL. Increased Yellow Saturation • Hue • Hue refers to the radial position of a color on the RGB color wheel. It determines the name given to the color, like red, yellow, blue, or purple, • Saturation • Saturation refers to the purity or intensity of a color. The lower the saturation level , the closer the color is to grayscale. Increased Yellow Luminance • Luminance • Also known as brightness or value, luminance determines how bright or dark a color is. It ranges from 0 to 100, with 0 being black. After a few more adjustments in the Basic panel and fine tuning the color we get the final image Processing time ~ 2 min Same photo using “Auto” adjustments such as JPEG result WARM AND COOL COLORS • The color wheel is split between warm and cool colors. Warm colors range from red to orange to yellow, while purple to blue to green hues are known as cool colors. This isn’t a clear-cut division as certain tones of green and purple may sometimes be considered part of the opposite temperature. • Warm colors tend to stand out, drawing our attention right away. That’s why, for example, danger and stop signs are often yellow or red. Because of this, warm colors in photography are also known as advancing colors. On the other hand, cool colors tend to fade into the background and are referred to as receding colors. • Knowing this, you can use color to give your images visual depth by combining advancing and receding colors. For example, a picture of a yellow fish with a blue water background gives off a much stronger sense of depth than the same shot would with a purple fish. THE EMOTION OF COLOR • One of the rarest and most powerful colors in nature, red is particularly important to photographers. Its historic associations between the color red and the emotions of passion and excitement make red a very active color. A little red goes a long way. • Orange is one of the more common in nature. It’s not just sunsets. The color brown is typically just a darker shade of orange, and it appears in nature all the time. Orange comes in a wide range of tonalities, from the dark brown of trees to the bright orange of a pumpkin. It conveys a feeling of warmth, and it is not as overpowering as red. • Yellow is the brightest and most optimistic color, particularly when it appears on its own and not as a blend with orange or green. However, it is this blended yellow we see most commonly in the world. Even bright green grass and vivid orange sunsets almost always have a component of yellow. • Even though blue is the most common color in nature, thanks to water and sky, green is the one we most associate with life. Our visual systems recognize more shades of green than any other color. So, your photographs can include multiple shades green, and almost endless variations thereof. Green is a familiar and soothing color. Because it represents the living world, it creates a sense of calm; green is the warmest of the cool colors. • Blue is associated directly with distance in the real world. Haze on the horizon, as well as the blue sky itself, both signal faraway, even unreachable destinations. Blue, on top of that, is not a busy color. It is calmer and less flashy. Dark blue and light blue convey somewhat different emotions. Dark blue can be strong and foreboding, as in a dark cloud. Light blue is gentler and more optimistic. But both are peaceful; even a blue storm usually has an element of calm to it. • Violet is perhaps the rarest color to see in its pure form in nature, usually found only in very specific sunsets or flowers. The color violet has a sense of tranquility to it – a calmness that is pleasant and often unexpected. If you ever have the chance to photograph a display of this rare color, like lupine flowers in bloom, make the most of it; violet is unusual enough that it makes your photos stand out. SATURATION IN POST PROCESSING oversaturated • One of the most important steps in post- processing is color correction. The tools present in software programs are nearly endless, allowing you to tweak any little detail needed to bring your images’ true colors to life. • One of the most important things about post- processing color in photography is knowing when to stop. oversaturated • Over saturated altered colors, especially in landscapes, look like they are from another planet. • Above all things, remember that bad color correction can feel off-putting. Vibrant color EXTRA SLIDES KEY TERMS FOR COLOR Hue • Hue is the term most people use to describe different colors, such as red, orange, purple and so on. Hue is synonymous with wavelength most of the time, except for the non-spectral colors like pink and brown. Brightness • One of the key factors in color psychology is the level of brightness in a color. You will also see brightness referred to as ‘va lue’. It represents the quality of a color from dark to light, or when it comes to pigments, how much black or white exists is in a co lor. • The three main terms used to describe brightness are shade, saturation, and tint, which are defined as follows: Shade • The shade describes how dark a color appears, as it moves from its vivid color towards black. As a color becomes more shaded, it’s synonymous to having the lights slowly dimmed, till you can only see black. Saturation • Saturation describes how a color transitions from its most vivid appearance towards a grey appearance. A highly saturated color is a vivid, pure hue. As we desaturate the color, it becomes less saturated and starts to appear gray and washed out. Tint • As the vivid color moves towards white, we have tint. It’s the opposite of shade. ADDITIVE AND SUBTRACTIVE COLOR • There are two ways to combine colors. First, by merging colored light, and second, by merging colored pigments. Among the color models in Figure 5, the one additive model builds colors by adding light, while the two subtractive models build colors by subtracting light. • Building color by combining light is called additive because you’re adding colored lights together. As you add more and more colored lights, the overall color gets whiter and whiter.

  • OSHER Color 2021
    OSHER Color 2021 Presentation 1 Mysteries of Color Color Foundation Q: Why is color? A: Color is a perception that arises from the responses of our visual systems to light in the environment. We probably have evolved with color vision to help us in finding good food and healthy mates. One of the fundamental truths about color that's important to understand is that color is something we humans impose on the world. The world isn't colored; we just see it that way. A reasonable working definition of color is that it's our human response to different wavelengths of light. The color isn't really in the light: We create the color as a response to that light Remember: The different wavelengths of light aren't really colored; they're simply waves of electromagnetic energy with a known length and a known amount of energy. OSHER Color 2021 It's our perceptual system that gives them the attribute of color. Our eyes contain two types of sensors -- rods and cones -- that are sensitive to light. The rods are essentially monochromatic, they contribute to peripheral vision and allow us to see in relatively dark conditions, but they don't contribute to color vision. (You've probably noticed that on a dark night, even though you can see shapes and movement, you see very little color.) The sensation of color comes from the second set of photoreceptors in our eyes -- the cones. We have 3 different types of cones cones are sensitive to light of long wavelength, medium wavelength, and short wavelength.

  • Color Schemes Are Combinations of Colors
    Color is the reflection of light off of an object into our eyes. Our eyes then read the speed of the light and tell us which color that object is. There are two major categories under the heading of color, they are: 1. Neutrals 2. Colors Neutrals are (combinations of) black and white and all grays Colors consist of: Primary colors Secondary colors Intermediate colors also known as Tertiary colors Primary Colors: are the basic colors that you cannot make by mixing. They are natural colors found in nature. They are red, yellow, and blue. Secondary Colors: are made by mixing any two secondary colors. The secondary colors are orange, violet and green. Intermediate Colors: are made by mixing a primary and a secondary color. The secondary colors are, red-violet, blue-violet, blue-green, yellow-green, yellow-orange and red-orange. Color schemes are combinations of colors. There are many different types of color combinations, however, only four of the most basic are included here. They are: • Complementary colors • Analogous colors • Warm & Cool colors • Monochromatic colors Complementary Colors: are any two colors that are opposite each other on the color wheel. Analogous Colors: are any two colors that are adjacent to (or next to) each other on the color wheel. Warm & Cool Colors: warm colors are those colors that contain combinations of red and yellow. There are six. To help you remember what a warm color is, think of the sun or fire. Cool colors are those colors that contain green and blue. There are six of these too.

  • Color Theory for Photographers As Photographers, We Have a Lot of Tools Available to Us: Compositional Rules, Lighting Knowledge, and So On
    Color Theory for Photographers As photographers, we have a lot of tools available to us: compositional rules, lighting knowledge, and so on. Color is just another one of those tools. Knowing and understanding color theory — the way painters, designers, and artists of all trades do — a photographer can utilize color to their benefit. Order of colors This may cause some flashbacks to elementary school art class, but let’s start at the beginning: The orders of colors. There are three orders: Primary, Secondary, and ​ Tertiary colors. The primary colors are red, yellow, and blue. That is to say, they are the three pure colors from which all other colors are derived. If we take two primary colors and add combine them equally, we get a secondary color. Finally, a tertiary color is one which is a combination of a primary and secondary color. Primary Colors: Red, yellow, and blue are what we call “pure colors.” They are not ​ created by the combining of other colors. Secondary Colors: A 50/50 combination of any two primary colors. Example: Red + ​ Yellow = Orange. Tertiary Colors: A 25/75 or 75/25 combination of a primary color and secondary color. ​ Example: Blue + Green = Turquoise. Now, how do the orders of colors help a photographer? Well, by knowing the three orders, we can make decisions about which colors we want to show in frame. The Three Variables of Color Now that we’ve been introduced to the orders of the colors, let’s look at their variables. Let’s start with hue. Hue Hue simply is the shade or name of the color.

  • Glossary of Art Terms
    Glossary of Art Terms Abstract – a style of art in which shapes, designs, textures and colors are represented in a way that may look unrealistic, but that emphasizes moods or feelings. Abstract art is characterized by the use of geometric lines and shapes and bright, bold colors. Aesthetic – pertaining to the artistic and beautiful, a perception that something is pleasing to the eye. Analogous Colors – colors that are closely related. For example, blue, blue-violet and violet all have the color blue in common. Asymmetrical – having a kind of balance in which the two sides of an artwork are not exactly alike, but still look balanced. Background – the parts of an artwork that lie in the distance and appear to be behind objects in the foreground. Balance – a principle of design. The arrangement of elements in a work of art (including size and number of objects) that achieves a sense of equality. Bird's Eye View – a scene shown from high up in the air as a bird in flight might see it. Brush stroke – a line, shape or texture created by applying paint to a surface with a paintbrush in a particular way. Calligraphy – the art of writing letters and words in an ornamental style using brushes or pens. Collage – work of art created by gluing bits of paper, fabric, scraps, photographs or other materials to a flat surface. Color – An element of art. The hue, value, and intensity of an object. The primary colors are red, blue and yellow: every color except white can be created from various blending of these three colors.
