Section 2 — Control Panel Descriptions
A secondary hue selector in the Model 3000 adds a color vector
opposite the background hue to selected foreground objects. This
can be used to tint foreground objects to counteract the color from
the background. The secondary hue selector affects only the
chroma suppression of the foreground. It does not contribute to
the background key signal nor to luminance suppression. This
function is enabled by the SECONDARY COLOR SUPPRESS
selection in the Chroma Key/Secondary Color menu.
Refer to the Menu Descriptions section of this manual for
additional features provided by the Chroma Key menu.
