Hue and Saturation Adjustment
The color adjustment feature lets you adjust hue and saturation for the primary and the secondary
colors. Each adjustment affects those areas in the image where the adjusted color predominates.
For example, the adjustment of red affects the colors in the image with a predominantly red
component.
Keep in mind that when you adjust a color, the nearest neighboring colors in the color hexagon will
also be affected to some degree. For example, when you adjust red, yellow and magenta will also
be affected.

Hue: In the color hexagon, the adjustment of hue can be considered as a rotation between
hues. Primary colors can be rotated towards, and as far as, their neighboring secondary
colors. And secondary colors can be rotated towards, and as far as, their neighboring primary
colors.
For example, when red is rotated in negative direction towards yellow, then, for example, purple
in the image can be changed to red and red in the image can be changed to orange.
Red can be rotated as far as yellow, where red will be completely transformed into yellow.
When red is rotated in a positive direction towards magenta, then, for example, orange in the
image can be changed to red and red in the image can be changed to purple.
Red can be rotated as far as magenta, where red will be completely transformed into magenta.

Saturation: Adjusting saturation changes the colorfulness (intensity) of a color. The color
adjustment feature lets you adjust saturation for the primary and secondary colors.
For example, if saturation for red is increased, the colorfulness of red colors in the image will
increase. If red is set to minimum saturation, red will be replaced by gray for "red" colors in the
image.

to 0. The default value after camera reset or power up is close to 0.
You can use the Color Adjustment Saturation parameter to set the saturation for the selected color
as a floating point value in a range from 0.0 to +1.99219. Saturation is not changed when the
