Beginning with some thoughts on how we define the concept of color, Richard explains various methods people in history have used to systemize color. These systems include the additive and subtractive color wheels, which are addressed as metaphorical maps of color. The basic vocabulary we use to describe color - hue, value and saturation - are explained through illustrative and graphic means. The majority of this lecture is concerned with color harmonies and contrasts, with references to over 350 paintings. This lecture is intended to do more than spend time defining this list of terms - advice is offered about how to best use these "Mechanics of Color" to your advantage, and a few traps to avoid.
