COLOR THEORY – Additive Color I build a painting by putting little marks together— some look like hot dogs, some like doughnuts. -Chuck Close COLOR THEORY – Additive Color PRIMARY yo Y yg Light Hue SECONDARY O G Object Value tertiary ro COLOR bg Observer Intensity - B Temperature R rv V bv The mixing color wheel deals with subtractive color. It doesn’t explain the interaction of colored light.

Colors get brighter & more intense as they mix.

Cone (color) receptor cells in the human eye are sensitive to RGB.

All color systems have hues that are out-of-gamut in other systems. NO system is perfect.

COLOR THEORY – Additive Color PRIMARY yo Y yg Light Hue SECONDARY O + G Object Value tertiary ro COLOR bg Observer Intensity - B Temperature R rv V bv Partitive Color small bits of color mix as light before they are perceived. A brick wall as seen from far away. COLOR THEORY – Additive Color PRIMARY yo Y yg Light Hue SECONDARY O + G Object Value tertiary ro COLOR bg Observer Intensity - B Temperature R rv V bv Partitive color examples: Ben-Day Dots Small, semi-transparent dots used in color printing. Four Color Process (CMYK) Standard color printing uses only 4 colors: Cyan Magenta Yellow - Secondary colors of light. Black - to provide a wider value range.

COLOR THEORY – Additive Color Seurat used color vibration to create Pointillism. Chuck Close images
