Spin Randomness: A dial that defines an amount of variance in the spin of generated
particles. A value of 0 results in no variance—all particles from the selected cell spin at
the same rate. A value greater than 0 introduces a variance defined by the Spin parameter,
plus or minus a random value falling within the Spin Randomness setting.
Additive Blend: By default, particles are composited together using the Normal blend
mode. Select this checkbox to composite all overlapping generated particles together
using the Additive blending mode. This blending occurs in addition to whichever
compositing method is already in use. The result is that the brightness of overlapping
objects is intensified. This effect applies to the particle system itself—the blend mode of
the emitter determines how the result of the emitter is blended into the scene.

Color Mode: A pop-up menu that determines if and how particles are tinted. There are
five options:
Original: Particles are generated using their original colors. When Original is chosen,
the Opacity Over Life parameter appears. Adjust the opacity controls to animate changes
to the opacity of particles over their lifetime.
For more information on using the gradient controls, see Using the Gradient Editor.
