The Color Wheel: Primary Colors • Primary Colors: Red, yellow and blue • In traditional color theory, primary colors can not be mixed or formed by any combination of other colors. • All other colors are derived from these 3 hues. The Color Wheel: Secondary Colors • Secondary Colors: Green, orange and purple • These are the colors formed by mixing the primary colors. The Color Wheel: Tertiary Colors • Tertiary Colors: Yellow- orange, red-orange, red-purple, blue-purple, blue-green & yellow-green • • These are the colors formed by mixing a primary and a secondary color. • Often have a two-word name, such as blue-green, red-violet, and yellow-orange. Color Context • How color behaves in relation to other colors and shapes is a complex area of color theory. Compare the contrast effects of different color backgrounds for the same red square. Color Context • Does your impression od the center square change based on the surround? Color Context Additive colors • Additive: Mixing colored Light Subtractive Colors • Subtractive Colors: Mixing colored pigments Color Schemes Color Schemes • Formulas for creating visual unity [often called color harmony] using colors on the color wheel Basic Schemes • Analogous • Complementary • Triadic • Split complement Analogous Color formula used to create color harmony through the selection of three related colors which are next to one another on the color wheel. Complementary Color formula used to create color harmony through the selection of two unrelated colors which are directly across from one another on the color wheel. Triadic A triadic color scheme uses colors that are evenly spaced around the color wheel. Triadic color schemes tend to be quite vibrant. To use a triadic harmony successfully, the colors should be carefully balanced - let one color dominate and use the two others for accent. Split Complement variation of the complementary color scheme. In addition to the base color, it uses the two colors adjacent to its complement. Has strong visual contrast, but less tension. The split-complimentary color scheme is often a good choice for. Color Applications and Effects • Keying the composition • Color Temperature • Color ‘Charm’ Keying the composition • Another way to achieve color harmony is to ‘key’ the composition, by adding a single color, usually the color of the light source, to all colors in the composition. • Adds an analogous relationship to all colors. And mimics light sources Color temperature • Color Temperature: based on our natural association. • Cool Colors: Colors on the green-blue side of the color wheel. • Warm Colors: Colors on the Red-yellow-orange side of the color wheel. Color Temperature: Warm vs. Cool • Warm colors seem to charge forward in a composition, while cool colors tend to recede. Color Temperature: Warm vs. Cool Objects in warm light have cooler colored shadows; objects in cool light have warmer colored shadows. Color ‘Charm’ • The ‘push-pull’ effect caused by competing color contrasts often creates an optical illusion of movement called color ‘charm.’ Psychological dimensions of color: Hue Color Value and Saturation • Hue: Determined by The wavelength of light as it is perceived by the eye. Color temperature • Color Temperature: based on our natural association. • Cool Colors: Colors on the green-blue side of the color wheel. • Warm Colors: Colors on the Red-yellow-orange side of the color wheel. Color Temperature Dan Flavin: Is it art? • http://www.youtube.com/watch?v=QXyOB1XCfd4 Primary Colors • Primary colors: red, yellow, and blue. • These colors mix to make the others. Secondary • Secondary colors: are derived from mixing two primary colors. Complementary Colors • Complementary: Contrasting colors located on opposite sides of the color wheel.

  • 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.

  • Marianne Times Column
    Portrait of the Artist: Marianne F. Buckley Curran By Theresa Brown “Portrait of the Artist” is a bi-weekly series introducing Hull Artists to the community by asking each artist to answer 10 questions that will give you a glimpse into their world. Marianne Buckley-Curran’s connection with Hull Artists goes back to its early founding years and the seasonal “Studio at the Beach” in the old MDC garage in the late ‘90s. Like many other Hull Artists, some of her earliest memories are of creative activities and a connection to an artistic family member. In her case a grandfather, who was a Lighthouse Keeper, sign painter, and artist, taught Marianne how to properly use an oil paint brush as a small child. Although art making continued to be an important part of Marianne’s life, practicality and natural athleticism led her to pursue a college degree and career in Physical Education. While taking a break from teaching to raise her family, Marianne was able to link her knowledge and love of art to a part time entrepreneurial venture as an artist agent. She arranged exhibition of works by other artists in area businesses as well as organized and operated local art shows. ****( my strategy was to learn the business of art while I was developing my own artistic vision ) Always surrounded by the artistry of others, Buckley-Curran began to question why she wasn’t exhibiting her own work and started entering her paintings in juried shows. Success in these shows encouraged her to refocus on making art and to study with local painter John Kilroy.

  • Regionalism and Local Color Fiction in Nineteenth-Century Us Literature

Se presenta un panorama general a fin de contextualizar el regionalismo y el localismo como movimientos literarios y como subgdneros literarios en el desanollo de la literatura estadounidense del siglo diecinueve, mediante el andlisis de los contextos hist6ricos, sociales, politicos y literarios que inicialmente propiciaron estas dos tendencias literarias y posteriormente influyeron en su desapariciSn. Tambidn se examina el contenido cultural y aporte literario de estas etiquetas, asi como la posibilidad de intercambiarlas. ABSTRACT This is the first in a series of articles dealing with the interrelationships of female authorship and space/place in U.S. literature. This article provides an overview for contextualizing regionalism and local color both as literary movements and as literary subgenres in the development of nineteenth-century U.S. literature by exploring the historical, social, political, and literary environments which initially propitiated and later influenced the demise of these two literary tendencies. It also examines the cultural and literary import of these labels, as well as their possible interchangeability. Place and space are components of human reality at its most fundamental level. InThe Poetics of Space, Gaston Bachelard affirms that our home is "our first universe, a real cosmos in every sense of the word" (1994:4). We construct a personal identity not only for and within ourselves, but inevitably grounded in our context, at the same time that the environment constmcts us.

  • 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.

  • White Paper the Twilight Zone
    White paper The twilight zone …a journey through the magic realm of color spaces, gray shades, color temperatures, just noticeable differences and more Goran Stojmenovik Product Manager Barco Control Rooms division The whole story behind display specifications and human vision (2) Abstract Our world and the displays representing it are not black and white, as someone might think when seeing a display spec consisting only of luminance and contrast. There is much more, there is a whole world of gray shades, color spaces, color temperatures, contrast sensitivities, just noticeable differences. Knowing what “brightness” and “luminance” are and being able to distinguish them, knowing what influences on-screen contrast of a display, and knowing how the eye adapts to changes in luminance levels – these are factors you should have learned from the first part of this white paper. Here, we will go into deeper waters of human vision, to explain when we perceive a display as a good display, and what are the requirements posed by the human visual system to create a good display.
