Revision History
Revision $Revision: 2403 $ 2007-10-23 ude

In this tab, you can specify how to treat gray. By default, grey is not considered as a color and is not taken in account by the rotation. Here, you can convert slightly saturated colors into grey and you can also convert grey into color.

Grey Color Circle

At center of this color circle is a small "define circle". At center, it represents grey. If you increase grey threshold progressively, colors with saturation less than this threshold turn to grey.

Then, if you pan the define circle in the color circle, or if you use input boxes, you define Hue and Saturation. This color will replace all colors you have defined as grey. But result depends on Grey Mode too.

Grey Mode

The radio buttons Treat As This and Change As This determine how your previous choices will be treated:

  • With Change to this, grey will take the color defined by the define circle directly, without any rotation, whatever its position in the color circle.

  • With Treat as this, grey will take the color defined by the define circle after rotation, according to "From" and "To" choices you made in the Main tab. With this option, you can select color only in the "From" sector, even if it is not visible in Grey tab.

Gray Threshold

You specify there how much saturation will be considered grey. By increasing progressively saturation, you will see an enlarging circle in color circle and enlarging selected areas in Preview if "Continuous update" is checked. In a black to white gradient,you can see enlarging color replacement as you increase threshold very slowly.

Black to White gradient, progressively filled with color, as threshold increases.
