- Theoretically, combining primary colors in equal amounts should produce black, but in practice, it results in a muddy brown
Secondary and Tertiary Colors
- Secondary colors are obtained by mixing two primary colors in equal proportions
- Mixing cyan and yellow produces green
- Combining magenta and yellow results in red
- Mixing cyan and magenta creates blue
- Tertiary colors are created by mixing a primary color with an adjacent secondary color
- Examples include red-orange, yellow-green, blue-green, blue-violet, red-violet, and yellow-orange
Light vs. Pigment in Subtractive Mixing
- Subtractive color mixing works with pigments or dyes, not light
- Pigments absorb certain wavelengths of light and reflect others
- White light contains all wavelengths of visible light
- Pigments selectively absorb wavelengths, subtracting them from the reflected light
- The reflected wavelengths determine the perceived color
- In subtractive mixing, the more colors mixed together, the darker the resulting color
- Opposite of additive mixing, where combining colors results in a lighter color
