Color Balance button

Click this button to evoke the Color Balance dialog box:

In this dialog box, you can change the mixture of colors of an image to either emphasize or diminish certain colors.

The components are introduced below:

Channel

This is where you can select the specific channel to be adjusted.

Adjustment Area

You can drag the triangles or enter the value (from 0 to 100) in the box directly to adjust.

To adjust the color balance, you will want to first select the channel you want to adjust, then drag the triangles under the three color bars. In addition, you can also enter the desired values directly into the three entry boxes to the right of the color bars to adjust the color balance.

As an example, if the color of the brighter area in the original you scan appears to be bluish, you can eliminate the bluish effect by first selecting Highlight as the channel, and then dragging the triangle below Cyan-Red bar to the right; alternatively you can drag the triangle below the Yellow-Blue bar to the left.

When you get the desired effect, click on the OK button to confirm your settings and close the dialog box. If you are not satisfied with the adjustment, you can click on the Reset button and the settings will return to the default values so you can reset them, or you can click on the Cancel button to cancel your settings and close the dialog box.
