Corel Painter 269
Use the Adjust Color dialog to change the hue,
saturation, and value of an image.
To adjust colors:
1 Select a layer or area of the canvas.
If you want to adjust colors in the
entire image, select nothing.
2 Choose Effects menu > Tonal
Control > Adjust Colors.
3 In the Adjust Color dialog box,
choose one of the following
methods from the Using pop-up
menu:
• Uniform Color adjusts all pix-
els equally.
• Paper uses the selected paper
grain to control the color
adjustment.
• Image Luminance uses the
luminance of the image as the
model for color adjustment.
Areas of greater luminance are
adjusted more.
• Original Luminance uses the
luminance of the clone source
as the model for color adjust-
ment. If you have not set up a
clone source, the current pat-
tern is used.
• [Alpha channel] or [Layer
mask] uses the selected alpha
channel or layer mask as the
model for controlling color
adjustment. For example, a
black-to-white gradation in the
channel or mask will allow you
to adjust the color progressively
across the image. Where the
channel or mask is black, colors
are not changed. Where the
channel or mask is white, the
adjustment applies fully. Tran-
sitional areas receive propor-
tional color adjustments.
4 Adjust the sliders to control the
overall hue, saturation, and value
levels in the selection.
• Hue Shift adjusts the colors of
the pixels by changing their
hue. Moving the slider to the
right shifts the hue counter-
clockwise on the color ring.
• Saturation adjusts the amount
of pure hue in the color. Mov-
ing the slider all the way to the
left creates a grayscale image.
• Value adjusts color brightness.
Moving the slider to the left
darkens colors.
You can see changes in the Preview
window. You can drag in the
Preview window to see different
areas of the image.
If you want to return the image or
selection to the way it was, click
Reset. This resets all of the sliders.
5 When you are satisfied with the
settings, click OK to apply the
effect.
