Trail Particle Color Format

The new trail particle introduced in the newest snapshot has its color given by a single ARGB integer (e.g.: 65029 would give a bright green).

The older dust particle however uses RGB with three values given (e.g.: [0, 1, 0] would give a bright green).

Please consider using a general color format for all particles. I would prefer the version used by the dust particle, as it is significantly easier to use.
