Chapter 3-16: Using GUI Features of the Image Editor

Making Color Selections

You can make color selections for graphical attributes by using one of three methods:

Swatch to select a specific color from a collection of color swatches (see below). Click on the desired swatch to select the color.

HSB to define a color based on a combination of hue, saturation and brightness . To select each of the three color components, click the appropriate radio button and use the slider to increase or decrease the component?s factor.

Hue is the actual color on a scale that starts and ends at red (0 and 359). Yellow is 60, green is 120, etc.

Saturation is the purity of the color, measured in percent from 0 to 100. At 0% saturation, hue is meaningless.

Brightness is measured in percent from black (0) to white (100). At 0% brightness, both hue and saturation are meaningless.

RGB to mix a color by selecting the quantity of red, blue and green from the three respective sliding scales that range from 0 to 255.

To use one of the three methods, click on the appropriate tab (swatches, hsb or rGB) at the top of the Select Color overlay. The swatch method is the default method.
