Object Color
By default, particles are created using the original colors of the image used as the cell. If
necessary, you can tint the emitted particles using the Color Mode parameters in the
Emitter and Particle Cell Inspectors. Choose between tinting all particles with a single
color or creating a gradient tint that changes color over time. You can also choose to
apply a Library gradient to the particles. Tinting particles applies the tint color uniformly
over the entire particle system.
