Intro to Color Physics
Isaac Newton: discovered color was a function of light, all color is contained in sunlight
In the case of a green leaf, all colors in sunlight are absorbed into the leaf except for green, which is reflected toward our eyes. If all wavelengths are absorbed we see black. If all wavelengths are reflected we see white.
These are the primary colors in the subtractive (pigment based) color system. Mixing two primary colors produces Secondary colors: Orange, Green, Purple. Primary colors cannot be mixed from other colors.
Value: light or dark in colors
Colors have inherent values. In these Chromatic Value Scales the step at Full Saturation (full purity) arrives at different point in each scale. In yellow, it is step 4, red: step 7, blue: step 9. This is because pure blue is inherently darker than pure yellow.
A combination of colors based on variations of value and saturation of a single hue. Perhaps some neutrals are also included to add variety and contrast.
