Note: if the hue component of the randomized modulation color is outside of the [0, 1] interval, it is taken modulo 1.0. If any of the saturation, value or alpha components is outside of the [0, 1] interval, its value is clamped.
Note: the modulation itself happens in RGBA space. Each of the RGBA components specified by the modulation is multiplied to the corresponding component specified by the particle material.
