Shift Color
The Shift Colors effect shifts colors on an
image with consequent saturation and lightness adjustment.
The effect has the following controls that are represented
by gradient lines:
-
The middle gradient line defines the effect
application area.
The effect application area (the color/colors that will
be shifted) is defined by a gradient line with 4 sliders under it: two outer
and two inner sliders.
The colors between the inner sliders will be affected
to the full extent. The colors between the inner and the outer sliders will
change less (the farther from the inner slider, the weaker is the effect
influence). The colors outside the outer sliders will stay the same.
Move the sliders to change the effect application area.
For this purpose, bring the cursor to one of the sliders, left-click on
it, and drag it to the required position on the line.

To move all 4 sliders at once, bring the cursor in the
middle of the inner sliders, left-click on it, and, keeping the left mouse
button pressed, move the sliders to the required position.

The upper gradient line regulates the
color shift. Bring the cursor to the gradient line, left-click on it,
and, keeping the left mouse button pressed, move the slider to the left/right,
in such a way, that the required colors are above the effect application
area.

- The lower gradient line shows the result of the color shift.
Compare the middle and the lower gradient lines to see which
color and how it will be changed.
Below is an example of the effect application. The blue color
was replaced by red, other colors stayed the same.

All Colors. When the check-box is enabled, all image
colors are affected by the change. In this case only two gradient lines are
displayed: the lower one shows the original color range, while the upper gradient
line adjusts the color shift.
 Applies the effect to all colors on an image The Saturation parameter changes the intensity
of the image colors. The values of the parameter vary between 0 (grayscale)
to 200 (bright colors). By default the parameter is set to 0.
The Lightness parameter changes the overall
lightness of the image, making it darker or lighter.
