The color dialog
The color dialog lets you specify color in one of
two different color models: HSB or RGB. HSB is the more
intuitive color model.
In the HSB color model, colors are specified using three parameters
called Hue, Saturation and Brightness. Hue specifies the color
of the color, such as blue or yellow. Saturation specifies the
concentration of the selected hue with respect to the overall
intensity. Less saturated color has some white light mixed in.
If the saturation is set to 0, you get a shade of gray. Brightness
specifies the overall intensity of light. If the brightness is
set to 0, you get black.
In the color dialog, different hues are arranged
around a color wheel. As you move towards the center of this wheel,
saturation decreases. The dialog also has a brightness bar. As
you move upwards on the brightness bar, the brightness increases.
To select a color, first select a hue by clicking
at an appropriate angle on the color wheel. Now adjust the saturation
by moving towards or away from the center. Next click on the brightness
bar. Move up or down to adjust the brightness. The currently chosen
color is visible in the little square next to the brightness bar.
Click OK to select the color.
