The color you see for an object depends on the mix of light frequencies that reach your eye. That mix, in turn, depends on two things: the frequencies that the object absorbs, and the frequencies in the original light source. The figure on this page shows how this works with reflected light. If a surface doesn’t absorb any colors, then all the colors are reflected, and you see white. If it absorbs all red and only red, then it reflects green and blue, so you see cyan, and so on.
