Because most of the color properties in most actions are multipliers,
setting all of them to the same color does not make the effect that color.
Instead, it will make the color much deeper/darker unless it's just white.
This function can be used to filter properties to assign the target color
to. It does this by defining "primary" and "secondary" color properties
for all actions with colors. If primary color properties are set to the
target color and secondary color properties (all non-primary ones) are set
to white, the final color will match the target color exactly.
For example, BillboardEx has four color properties:
This function will return false for color1, color2, and bloomColor, but
true for color3. Since the product of color1, color2, and color3 is the
actual color of the particle, and the bloom color is the product of the
particle color and bloomColor, setting only color3 to the target color
and the RGB values for the rest of the properties to white will make the
particle's final color match the target color.
