Problem

Colors blend with the background
Show blending graphs in AB (top examples)
Show blending graphs in LAB (new graphs)

Existing Solution (Naive RGB)

Often results in zero-values (lumped in black)
Substracts colors in an incorrect color space (hue changes)
Ignores the influence of the display material
