Hue and Saturation Adjustment
The color adjustment feature lets you adjust hue and saturation for the primary and the secondary
colors. Each adjustment 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 colors on each side of it in the color hexagon will
also be affected to some degree. For example, when you adjust red, yellow and magenta will also
be affected.
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.
Adjusting saturation changes the colorfulness (itensity) 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 grey for "red" colors in the
image.
Enabling and Setting the Color Adjustments
You can enable or disable the color adjustment feature by setting the value of the Color Adjustment
Enable parameter to true or false.
You can use the Color Adjustment Selector parameter to select a color to adjust. The colors you
can select are: red, yellow, green, cyan, blue, and magenta.
You can use the Color Adjustment Hue parameter to set the hue for the selected color as a floating
point value in a range from -4.0 to +3.96875.
As an alternative, you can use the Color Adjustment Hue Raw parameter to set the hue as an
integer value on a scale ranging from -128 to +127. This integer range maps linearly to the floating
point range with -256 being equivalent to -4.0, 32 being equivalent to 1.0, and +255 being
equivalent to +3.96875.
.
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 +3.98438.
As an alternative, you can use the Color Adjustment Saturation Raw parameter to set the saturation
as an integer value on a scale ranging from 0 to 255. This integer range maps linearly to the floating
point range with 0 being equivalent to 0.0, 64 being equivalent to 1.0, and +255 being equivalent to
+3.98438.
