Terms for January 12

• Subtractive Color – Color seen in pigment as the result of reflected light.  Subtractive color primaries are red, yellow, and blue, and, when they are combined, they produce a dark tone that approaches black.
• Additive Color – Color as seen in light.  Additive color primaries are red, green, and blue (blue violet), and, when they are combined, the result is white light.
• Co-Primaries – The result of the subdivision of the (subtractive) primary triad into three pairs consisting of cool and warm versions of each hue.  The use of co-primaries greatly extends the potential range of mixed colors.
