Optical Color Mixing
Definition
Optical color mixing is the perceptual phenomenon where adjacent small marks of pure color are synthesized into a unified composite hue by the human visual cortex at a distance, producing greater luminance than subtractive pigment mixing.
Key Characteristics
- Preserves spectral purity and perceived brightness
- Distance-dependent perceptual resolution
- Underpins CRT, LCD, and RGB digital displays
Applications
- Dithering algorithms in computational graphics
- Palette reduction and color quantization in generative art
- Digital screen pixel arrangements (subpixel rendering)
