Chapter 8 Working with Particles 729
 Colorize: Particles are tinted using the color specified in the Color parameter.
Additional Color and Opacity Over Life parameters appear.
 Over Life: Particles are tinted based on their age. The Color Over Life gradient editor
defines the range of color that each particle assumes as it ages, beginning with the
leftmost color in the gradient, and progressing through the range of colors until
finally reaching the rightmost color at the end of its life.
When Over Life is selected, the Color Repetitions slider becomes available. Drag the
slider to increase the number of times the gradient is repeated over the life of the
particle.
Note: For more information on using gradient controls, see “ Using the Gradient
Editor ” on page 1033.
