Perceptually Linear Color Spaces
CIE created 2 perceptually linear (uniform) color spaces:
- CIE lab and CIE L*u*v*
- CIE L*u*v*
- L = lightness
- u* = red-green
- v* =blue-yellow
- Not commonly used- Why?
- Ignorance
- Complexity of conversion
- Need cube root - expensive
- Need tristimulus coordinates for monitor
