Know the Color Wheel Primary Color
Introduction to Color/Hue Theory With Marlene Oaks Color affects us psychologically in nature, clothing, quilts, art and in decorating. The color choices we make create varying responses. Being able to use colors consciously and harmoniously can help us create spectacular results. Know the Color Wheel Primary color Primary color Primary color The color wheel is the basic tool for combining colors. The first circular color diagram was designed by Sir Isaac Newton in 1666. Primary, Secondary and Tertiary Colors Color theory in regards to light says that all colors are within white light—think prism, and black is devoid of color. In pigment theory, white is the absence of color & black contains all colors. We will be discussing pigment theory here. The primary colors are red, yellow and blue and most other colors can be made by various combinations of them along with the neutrals. The three secondary colors (green, orange and purple) are created by mixing two primary colors. Another six tertiary colors are created by mixing primary and secondary colors adjacent to each other. The above illustration shows the color circle with the primary, secondary and tertiary colors. 1 Warm and cool colors The color circle can be divided into warm and cool colors. Warm colors are energizing and appear to come forward. Cool colors give an impression of calm, and appear to recede. White, black and gray are considered to be neutral.

Basic Color I
Basic Color I Up to this point we have explored and /or reviewed 4 several basic visual elements that will help develop a solid foundation for a Language of Painting. With a strong focus on the dynamics of paint application, we have connected simple dots with confident lines, con- figured lines into a wide array of shapes, and applied contrasting pigments in concert with varied pressures to yield seamless gradations of value. However, the previous chapter incorporated a new element that many find to be one of the most powerful tools for the creative endeavor-- color. The Painted Pressure Scale chapter, had us grow our palette from the sparse black and white that we have started with to include three colors: Red, Yellow and Blue. It is our hope that your experience generated a good number of questions from this inaugural color use. With this chapter we will take some first steps towards answering those questions. We will also revisit some of the color concepts you may already hold and introduce you to some of the more advanced methods for identifying, using and understanding this brilliant aspect of the artist’s salvo. On any initial investigation into color we are faced with a robust vocabulary of terms and concepts that may leave us somewhat confused. Like the many other aspects of our curriculum, we make a strong effort to simplify all of this. We will endeavor to make use of what you may have learned in the past and offer options for you to integrate color in the manner you wish into your creative process efficiently and effectively. -
Several Color Appearance Phenomena in Color Reproduction
2nd International Conference on Electronic & Mechanical Engineering and Information Technology (EMEIT-2012) Several Color Appearance Phenomena in Color Reproduction Qin-ling Dai1,a, Xiao-zhou Li2*,b, Ai Xu2 1 School of Materials Engineering (Southwest Forestry University), Kunming, China 650224 2 Key Laboratory of Pulp & Paper Science and Technology (Shandong Polytechnic University), Ministry of Education, Ji’nan, China, 250353 [email protected], bcorresponding author: [email protected] Keywords: color reproduction, color appearance, color appearance phenomena Abstract. Color perceived performance was influenced by various color appearance phenomena caused by varying viewing conditions in color reproduction process. It is necessary to do some research on the color appearance phenomena to represent the color appearance models qualitatively and quantitatively and accurate color reproduction easily. Only the phenomena were studied thoroughly, could the color transmission and reproduction be well performed. The color appearance and common color appearance phenomena of color reproduction were analyzed in this paper. And the basic theory of color appearance in color reproduction was also studied. Introduction High fidelity digital printing plays an important role in high fidelity color transmission and reproduction and it is one of the most important techniques to perform high fidelity color reproduction. High fidelity digital printing helps to perform accurate color reproduction of the original which can’t be performed because of paper and ink in traditional printing process [1]. In color printing, the color difference caused by paper, ink and viewing conditions is various. The difference is not only colorimetric difference but also different color appearance phenomena. While the different color appearance phenomenon is the leading factor to influence the color vision perceived. -

Color Combinations and Contrasts
COLOR COMBINATIONS AND CONTRASTS Full Value Color Combinations Above are 18 color combinations tested for visibility, using primary and secondary colors, of full hue and value. Visibility is ranked in the sequence shown, with 1 being the most visible and 18 being the least visible. Readability It is essential that outdoor designs are easy to read. Choose colors with high contrast in both hue and value. Contrasting colors are viewed well from great distances, while colors with low contrast will blend together and obscure a message. In fact, research demonstrates that high color contrast can improve outdoor advertising recall by 38 percent. A standard color wheel clearly illustrates the importance of contrast, hue and value. Opposite colors on the wheel are complementary. An example is red and green (as shown above). They respresent a good contrast in hue, but their values are similar. It is difficult for the human eye to process the wavelength variations associated with complementary colors. Therefore, a quivering or optical distortion is sometimes detected when two complemen- tary colors are used in tandem. Adjacent colors, such as blue and green, make especially poor combinations since their contrast is similar in both hue and value. As a result, adjacent colors create contrast that is hard to discern. Alternating colors, such as blue and yellow, produce the best combinations since they have good contrast in both hue and value. Black contrasts well with any color of light value and white is a good contrast with colors of dark value. For example, yellow and black are dissimilar in the contrast of both hue and value. -
WHITE LIGHT and COLORED LIGHT Grades K–5
WHITE LIGHT AND COLORED LIGHT grades K–5 Objective This activity offers two simple ways to demonstrate that white light is made of different colors of light mixed together. The first uses special glasses to reveal the colors that make up white light. The second involves spinning a colorful top to blend different colors into white. Together, these activities can be thought of as taking white light apart and putting it back together again. Introduction The Sun, the stars, and a light bulb are all sources of “white” light. But what is white light? What we see as white light is actually a combination of all visible colors of light mixed together. Astronomers spread starlight into a rainbow or spectrum to study the specific colors of light it contains. The colors hidden in white starlight can reveal what the star is made of and how hot it is. The tool astronomers use to spread light into a spectrum is called a spectroscope. But many things, such as glass prisms and water droplets, can also separate white light into a rainbow of colors. After it rains, there are often lots of water droplets in the air. White sunlight passing through these droplets is spread apart into its component colors, creating a rainbow. In this activity, you will view the rainbow of colors contained in white light by using a pair of “Rainbow Glasses” that separate white light into a spectrum. ! SAFETY NOTE These glasses do NOT protect your eyes from the Sun. NEVER LOOK AT THE SUN!

Color Mixing Ratios
Colour Mixing: Ratios Color Theory with Tracy Moreau Learn more at DecoArt’s Art For Everyone Learning Center www.tracymoreau.net Primary Colours In painting, the three primary colours are yellow, red, and blue. These colors cannot be created by mixing other colours. They are called primary because all other colours are derived from them. Mixing Primary Colours Creates Secondary Colours If you combine two primary colours you get a secondary colour. For example, red and blue make violet, yellow and red make orange, and blue and yellow make green. If you mix all of the primary colours together you get black. The Mixing Ratio for Primary Colours To get orange, you mix the primary colours red and yellow. The mixing ratio of these two colours determines which shade of orange you will get after mixing. For example, if you use more red than yellow you will get a reddish-orange. If you add more yellow than red you will get a yellowish-orange. Experiment with the shades you have to see what you can create. Try out different combinations and mixing ratios and keep a written record of your results so that you can mix the colours again for future paintings. www.tracymoreau.net Tertiary Colours By mixing a primary and a secondary colour or two secondary colours you get a tertiary colour. Tertiary colours such as blue-lilac, yellow-green, green-blue, orange-yellow, red-orange, and violet-red are all created by combining a primary and a secondary colour. The Mixing Ratios of Light and Dark Colours If you want to darken a colour, you only need to add a small amount of black or another dark colour. -
Development of a Methodology for Analyzing the Color Content of a Selected Group of Printed Color Analysis Systems
AN ABSTRACT OF THE THESIS OF Edith E. Collin for the degree of Master of Sciencein Clothing, Textiles and Related Arts presented on April 7, 1986. Title: Development of a Methodology for Analyzing theColor Content of a Selected Group of Printed Color Analysis Systems Redacted for Privacy Abstract approved: Ardis Koester The purpose of this study was to develop amethodology to compare the color choice recommendationsfor each personal color analysis category identified by the authorsof selected publications. The procedure used included: (1) identification of publications with color analysis systemsdirected toward female clientele; (2) comparison of number and names of categoriesused; (3) identification, by use of Munsell colornotations, the visual and written color recommendations ascribed toeach category; and (4) comparison of the publications on the basisof: (a) number and names of categories; (b) numberof color recommendations in each category; (c) range of hue value and chroma presented;(d) comparison of visual and written color recommendations by categoryand author. With the exception of comparison of publications onthe basis of written color recommendations, all components of themethodology were successful. Comparison of the publications used in development ofthe methodology revealed that: 1. The majority of authors use the seasonal category system. 2. The number of color recommendations per category was quite consistent within a publication but varied widely among authors. 3. There were few similarities in color recommendations even among authors using the same name categories. 4. There was poor agreement between written and visual color recommendations within all color categories. 5. There was no discernable theoretical basis for the color recommendations presented by any author included in this study. -

Color Wheel Page 1 Crayons Or Markers Color
Crayons or markers Color Wheel Cut-out (at the end of this description) String, about 3 feet Scissors Step 1 Color each wedge of the circle with a different rainbow color. Use heavy paper or a paper plate. Step 2 Cut out the circle, as well as the center holes (you can use a sharp pencil to poke through, too!). Step 3 Feed the string through the holes and tie the ends together. Step 4 Pick up the string, one side of the loop in each hand so the circle is in the middle. Wind the string by rotating it, in a “jump-rope”-like motion. The string should be a little loose with the circle pulling it down in the middle. Step 5 Move your hands out to pull the string tight to get the wheel spinning. When the string is fully unwound, move your hands closer together so it can wind in the other direction If it’s not spinning fast enough, keep winding! Step 6 As it spins, what happens to the colors? What do you notice? Color Wheel Page 1 What did you notice when you spun the wheel? You may have seen the colors seem to disappear! Where did they go? Let’s think about light and color, starting with the sun. The light that comes from the sun is actually made up of all different colors on the light spectrum. When light hits a surface, some of the colors are absorbed and some are reflected. We only see the colors that are reflected back.
