- Import the image (File > Import > Canvas Image ) or pick the layer to be
adjusted in the Canvas Layer Editor.
- Choose Paint Edit > Color Correction > Color Balance . The active layer is loaded
into the Color Balance window.
In this example we want
to add blue to the image — that is, convert the bright rust color
to a pure blue color.
- First we change the Color
Balance Factor slider to 100%. This shifts all hues to
pure color but maintains the current saturation and value (shading
range). Note how the thumbnail icons change to preview the possible
color balance changes when you click the thumbnail.
- Click the More Blue thumbnail
and watch the preview window update to the current adjustment value
as shown below.
- Now click the More Cyan thumbnail
and watch the preview window update to the current adjustment value.
Also note the rear orange indicator light has changed because no
mask layer or selection mask was used.
- The hue looks very strong, so click Clear at the
bottom of the window to restore the original image.
- Adjust the color balance amount to 50%
and click on the More Cyan thumbnail. This now
adds 50% cyan to the original image. If you click the thumbnail
again, it will add more cyan to the current selection.
The color balance window
encourages experimentation with color balance, so play and have
fun: when you are pleased with the preview, click Accept and
the current adjustment values are applied to the active image layer.
