Color Balance

"Color Balance" is one of the most helpful color adjustment tools.

1. If the edited document is layered select the uppermost layer in the Layers panel.
2. Apply the "Color Balance" command.

There appears dialog box allowing you to redistribute image color. The logic of this tool is based on RGB color model. That is, by adding a primary - red, green, or blue - color, you reduce amount of its complementary - cyan, magenta, or yellow - color. And vice versa.

3. For example, to remove yellow color cast, you move the lowest slider "blue'ward"; to decrease cyan, you move the uppermost slider "red'ward" (screenshot).

NB If the sliders "stick" to the cursor, don't move it during a second after releasing the mouse button.

4. The radio-buttons under the sliders let you restrict edited tonal range. For instance, you can try to add some yellow in the image shadows and decrease this color in the highlights.
5. Click "OK" to apply your adjustment.

If you need to modify the created adjustment layer's settings use Edit Adjustment Layer command.
