This document discusses color properties and color theory. It explains that color has three main properties: hue (the name of the color), intensity (brightness/purity), and value (lightness/darkness). It describes primary colors, secondary colors created by mixing primaries, and tertiary colors in between. It also covers color schemes like monochromatic, analogous, complementary, and triadic. Warm colors like red and yellow are named, as are cool colors like blue and green.
