i am currently learning Houdini 6.0
I was trying to use “color ” pop to control the color of the particles. but I was unable to use “color”pop's cop to control particles color. No mater what color I got in my cop “file” image, the particles emitted were all in red only. I tried to put “life” into “color” pop 's u and v values. But all particles were still in red! Does anyone know why?

the task that I want to learn is to use an image from cop to control the colour of the particles.

Thank you for your attention!
