Hi there,
To confirm my understanding, I have attached some screenshots below. Do you have a material that resembles this and a particle system similar to this one as well?
Can you provide a screenshot or a description of what the affected color looks like vs what you would expect it to look like?
[Image Removed][Image Removed]And changing the size in this example from 10 to 0.5 should exhibit some change in the color?
Kind Regards
