This
graph editor
dialog window is used to specify the color palette for the
node attributes
and
edge attributes
dialog windows.
You can select a color from the palette and modify the color value
by mixing the red, green and blue portion with the three sliders.
The first two colors in the palette (black and white) cannot be
selected, because they are fixed default values.
The selected color is also displayed in the large color field.
There you can see the RGB color value in HEX-notation.
