Defines a color map by which to colorize a raster particle layer, parameterized by the ["raster-particle-speed"] expression and evaluated at 256 uniformly spaced steps over the range specified by raster-particle-max-speed.
Defines defines the opacity coefficient applied to the faded particles in each frame. In practice, this property controls the length of the particle tail.
