Color Light is an essential practical guide to how color works in light. Written from the perspective of a theatrical lighting designer, it discusses how to see color, how to construct effective lighting palettes, and how to make use of both color filters and color-mixing LED fixtures to create compositions that work well with scenery and costumes to tell compelling stories. We are presently at the leading edge of a revolution in theatrical lighting, redefining how it can be used to create and communicate. Today's LED-based additive color-mixing fixtures require new methodologies and new ways of thinking, and Color Light directly addresses this technology's potentials and challenges. But underpinning lighting's many recent technological changes is the fundamental language of color that artists have worked with since the birth of humanity's artistic urges.
