e* 10 major hues: R, RY, Y, YG, G, GB, B, BP, P, PRH every color comes from these 10 hues* 3 ways of talking about color for Munsell:1. value: changes vertically and in increments of 12. chroma: changes horizontally and in increments of 23. saturation = value + chroma, changes diagonally * colors named by their hue value/chroma (H V/C) white light = RGB light in equal amounts color is a psycho physical response color is described in 3 ways:4. hue5. lightness6. saturation the human eye sees from 380 770 nm (NOT 400 700nm) ex./ 380__________550__________770 blue green red theories of how color is seen:2. psycho physical theory: invented by Young Helmhotlz, the eye sees three colors of light red, green, and blue that are reflected from objects.* three types of vision:2. trichromatic: sees all three colors2. dichromatic: sees only two of the three colors2. monochromatic: sees only black and white 2. opponent vision theory: invented by Herning, perceptors in the eye sees three sets of colors 4. red green5. yellow blue }psychological color sets6. black white* color after image = when an image that is one of these colors is looked at, when looked away the opposing color is seen pseudoisochromatic color test = colored images surrounded by grey pebblesH even people with good color sight can have bad color sight in certain conditions* photopic vision = daylight, good illuminance, eye peaks at 550nm* scotopic vision = low illuminance, eye peaks at 505nm scectrophotometer = machine that measures color, gives a curve of spectral reflectance * spectral reflectance = of the amount of each color of light reflected additive primary colors = red, green, blue = subtractive secondary colorsadditive secondary colors = cyan, magenta, yellow = subtractive primary colors* each color is created by the 2 colors next to it on the color wheelH cyan = no red, magenta = no green, yellow = no ...
