Adjusting colors

Gimp uses two colors for drawings, the foreground color and the background color. They can be found in the GIMP window and the adjustment can be done by simply clicking on them.

In the Colors window the colors can be selected by several ways. As an example let us see the HSB (HSV) method based on the characters of the colors. In the vertical column the shades can be seen (the spectra). Apparently, the green and blue shades are dominant and there are only a few brown and yellow shades.

Click on one shade and define the saturation and the brightness in the box. Numerical values can also be entered in the field if known.

Foreground color is black. Behind it the white rectangle is the background color.

Options

Most tools can work with several adjustments. They can be adjusted in the lower part of GIMP window. The GIMP window always offers the adjustment of the selected tool. The simplest way we can try it if we select more tools one after the other and check the options for adjustments appearing in the lower part of the window.

Gimp makes drawings with the foreground color selected. The eraser “creates drawing” with the background color.
