Choose Color dialog

1. Function

Choose Color dialog allows you to pick up any available in the system color.

Fig. 1. Choose Color dialog. Fig. 1. Choose Color dialog.

2. Options

To the left there are cells with Basic colors — select one of them if you want to use it as target color or as starting point for color selection.

Below there are cells with Custom colors — you can fill them with colors of your own. To add currently selected color to Custom colors click Add to Custom Colors button.

To the right there are HSL — Hue-Saturation-Luminosity — color selection controls. The rainbow rectangle is Hue-Saturation matrix: click inside matrix to select color. Moving matrix pointer horizontally you can change Hue value, and moving the pointer vertically you can change Saturation value. To change Luminosity use slider to the right of the Hue-Saturation matrix.

Color|Solid rectangle shows the selected color.

In Hue-Sat-Lum boxes you can type in target color in HSL format. In Reg-Green-Blue boxes you can type in target color in RGB format.

3. How to use

If you already know exactly what color you are about to select, use Hue-Sat-Lum or Reg-Green-Blue boxes to type in the color values.

If you are rather to go err-and-try way, start with selecting start color in Basic colors or in Hue-Saturation matrix. Then use Luminosity slider or Hue-Sat-Lum and Reg-Green-Blue boxes to get the perfect match.

If you want to have the selected color kept next time you open Choose Color dialog, select a cell in Custom colors and click Add to Custom Colors button — the cell will be filled with selected color and you will find it there next time you open the dialog.
