However, I looked at the flash effect I created for Zygo's Cinematic and got very excited about adding colour to that, but much to my dismay, either the change of mode from greyscale to RGB or simply the addition of colour values sets the texture to a simple square. Alas, I could have this in my OXP..

Is it possible for said flash to pick up colour in the same manner as nebulas?
If the same is true for stars I could add some subtle lighting efffects around them too!
