Foreground/Background Jitter and Control Specifies how paint varies between the foreground color and background

color.

To specify a percentage by which the color of the paint can vary, type a number, or use the slider to enter a value. To

specify how you want to control the color variance of brush marks, choose an option from the Control pop-up menu:

• Off Specifies no control over the color variance of brush marks.

• Fade Varies the color of paint between the foreground color and the background color in the specified number of

steps.

• Pen Pressure, Pen Tilt, Stylus Wheel, Rotation Varies the color of paint between the foreground color and the

background color based on the pen pressure, pen tilt, position of the pen thumbwheel, or rotation of the pen.

Hue Jitter Specifies a percentage by which the hue of the paint can vary in a stroke. Type a number, or use the slider

to enter a value. A lower value changes the hue while maintaining a close proximity to the hue of the foreground color.

A higher value increases the difference between hues.

Saturation Jitter Specifies a percentage by which the saturation of the paint can vary in a stroke. Type a number, or

use the slider to enter a value. A lower value changes the saturation while maintaining a close proximity to the

saturation of the foreground color. A higher value increases the difference between saturation levels.

Brightness Jitter Specifies a percentage by which the brightness of the paint can vary in a stroke. Type a number, or

use the slider to enter a value. A lower value changes the brightness while maintaining a close proximity to the

brightness of the foreground color. A higher value increases the difference between brightness levels.

Purity Increases or decreases the saturation of the color. Type a number, or use the slider to enter a percentage

between –100 and 100. At –100%, the color is fully desaturated; at 100%, the color is fully saturated.
