Color Cancel desaturates all colors of the fill signal which lie within a narrow angle
range around the key color in the color circle. Color Cancel is switched on by de-
fault after each automatic run (not Sel Auto).

Key Color delegates the parameters Luminance, Hue, Chroma and L-Offset
(with FGD-Fade) to the digipots.

To adjust the Key Color manually the following conditions must be given:

FGD Fade ”OFF”

Key ”ON” on background Black

Density, Clean up and Selectivity C at left stop

Selectivity L at right stop

Selectivity R at left stop

Luminance at left stop

Chrominance at left right stop

The adjustment is made in the following order:

Turn the Hue control until the key color is extensively achromatic. Then turn back
Selectivity roughly until approximately all key colors are covered.
Turn the Chroma control until the brightest color is just achromatic.
Turn the Luminance control until the key color is just black.

This setting can subsequently be optimized with the Selectivity, Density and
Clean up controls.

Delegates the parameter OLum S, ORight S and OLeft S to the digipots.

Delegates the parameter Chr S, Lum S, Right S and Left S to the digipots.
