Look Inside the EyeColor vision can be defined by what kind of color-detecting equipment exists inside the eye of a human or non-human animal. Some species see no colors, some see a few colors, some see all colors, and some see colors that are not visible to the typical human eye.The color-detecting equipment inside an eye is called a "cone." (The rods are for night vision.)
Additive Color Subtractive Color
RGBThe additive reproduction process usually ses red, green and bluelightto produce the other colors. Combining one of these additive primarycolors with another in equal amounts produces the additive secondarycolors cyan, magenta, and yellow. Combining all three primary lights(colors) in equal intensities produces white
In painting and other visual arts, two-dimensional color wheels or three-dimensional color solids are used as tools to teach beginners the essential relationships between colors. The organization of colors in a particular color model depends on the purpose of that model: some models show relationships based on Human color perception, whereas others are based on the color mixing properties of a particular medium such as a computer display or set of paints.
Tints, Shades, and TonesThese terms are often used incorrectly, although they describe fairly simple color concepts. If a color is made lighter by adding white, the result is called a tint. If black is added, the darker version is called a shade. And if gray is added, the result is a different tone.Tints - adding white to a pure hue : Shades - adding black to a pure hue: Tones - adding gray to a pure hue:
Warm and cool colorsThe color circle can be divided into warm and cool colors.Warm colors are vivid and energetic, and tend to advance in space.Cool colors give an impression of calm, and create a soothing impression.White, black and gray are considered to be neutral.
Some Formulas for Color HarmonyThere are many theories for harmony. The following illustrations and descriptions present some basic formulas . A color scheme based on analogous colors Analogous colors are any three colors which are side by side on a 12 part color wheel, such as yellow-green, yellow, and yellow-orange. Usually one of the three colors predominates. A color scheme based on complementary colorsComplementary colors are any two colors which are directly opposite eachother, such as red and green and red-purple and yellow-green. In theillustration above, there are several variations of yellow-green in the leaves andseveral variations of red-purple in the orchid. These opposing colors createmaximum contrast and maximum stability.
A color scheme based on natureNature provides a perfect departure point for color harmony. In the illustration above, red yellow and green create a harmonious design, regardless of whether this combination fits into a technical formula for color harmony. Color ContextHow 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.Red appears more brilliant against a black background and somewhat dulleragainst the white background. In contrast with orange, the red appears lifeless;in contrast with blue-green, it exhibits brilliance. Notice that the red squareappears larger on black than on other background colors.
• Different readings of the same color If your computer has sufficient color stability and gamma correction (link to Color Blind Computers) you will see that the small purple rectangle on the left appears to have a red-purple tinge when compared to the small purple rectangle on the right. They are both the same color as seen in the illustration below. This demonstrates how three colors can be perceived as four colors. Observing the effects colors have on each other is the starting point for understanding the relativity of color. The relationship of values, saturations and the warmth or coolness of respective hues can cause noticeable differences in our perception of color.
Color harmony and color meaningIt has been suggested that "Colors seen together to produce a pleasing affective response are said to be in harmony".However, color harmony is a somewhat misleading notion in that responses to color can be influenced by a range of different factors including individual differences (age, gender, etc.); cultural and social differences; as well as contextual, temporal and perceptual factors. Activity 1Search in internet .Choose one color and explain its meaning. Put differents axamples of works of art and explain them. Power point presentation in 3 sheets. Activity 2 Choose two or three geometrical shapes. Draw them with a graphite pencil. Use temperas to paint them.
