The Change Foreground Color Window

The color area is GIMP's basic color palette. It consists of two colors, the foreground color and the background color, and you can use it to choose colors for painting, writing, or filling. Clicking on any color brings up the Color Editor dialogs.

In the Change Foreground Color window, there are tabs allowing you to change the way in which color is represented. The most common is RGB mode (and HSV mode), which is set as default, resembled by the tab showing the GIMP icon. This color mode is found in most popular image editing programs.

The other color models are CMYK colors (four-color printing), color triangle, and watercolors (additive mixing colors).

Probably the most striking field is the square field on the left side, showing the hue of one chosen color. Clicking into this field lets you select the lightness levels for a color. Just click the desired hue to activate it. It will be shown as a new color in the Current field.

To the right of this field you find the RGB spectrum, if the radio button next to H is enabled. Click into this field or shift the mouse on it while holding the left mouse button down to preselect a color.

• Radio buttons The H radio button should be enabled for the default color display (see figure 3.31). The other radio buttons activate different views of the Hue field for selection.

• Sliders: You can move the H (for Hue) slider to produce alternative colors with the same lightness, using the settings in the figure. In general, the sliders serve to mix colors; an alternative for mixing colors is to select a color (or color range) with the mouse, as described earlier.

• Numerical entries: You can also type decimal values for Red, Green and Blue to set or mix a color. Optionally, in the HTML notation field, you can enter a 6-character hexadecimal value to set a specific color. This works well when you want to import an exact color from another program.

• Buttons: The OK button adds the selected color to the Toolbox and closes the Change Foreground Color dialog. The Reset button rejects the selected color and lets you select another color. The Cancel button closes the dialog without accepting the color you selected as the foreground or background color.
