Colored image in light function

Hello Folks,
Is it possible to input a full color texture into a light function for a movable spotlight? I’ve only had success with greyscale. Also hoping to have it work in volumetric light.

simply use 3 lights with red green and blue channels of you texture and light colors accordingly.

I will see how this scales, I am building a Realtime lighting simulator for the concert industry, and we are using thousands of dynamic lights in our scenes. I will also test to see if it participates in volume properly.
Thanks for the tip.

I made a tutorial that shows how to make colored light functions Fake Shadows and Colored Light Function - YouTube
