you can vary the location on the material map from which the particle color
is taken, thus changing the particle color in a predictable way over time.
The Mapping operator was designed primarily to be used with gradient maps,
although you can use it with any map you like. The procedure below describes
a recommended method for using the Mapping operator.

Procedures
Example: To animate particle coloring using the Mapping operator:
1
Open the Material Editor, and create a material that uses Gradient
Ramp as the Diffuse map.
2 On the map's Gradient Ramp Parameters rollout, make sure Gradient
Type is set to Linear.
3 Create a colorful gradient. The Mapping operator uses the colors in
left-to-right order as the U value increases from 0.0 to 1.0.
4 Add a Particle Flow Source object to the scene.
5 Open Particle View.
6 In Event 01, click the Speed operator and set Speed to 100.
7 In Event 01, click Display and set Type to Geometry.
8 Add a Material Static operator to Event 01, and then click the operator
in the event.
9 Drag the material you created from its Material Editor sample slot to the
button (labeled “None”) on the Material Static parameters rollout in
Particle View.
10 Add a Mapping operator to Event 01, and then click the operator in the
event.
