I have written a shader variant of the URP SimpleLit. It multiplies a diffuse color with vertex colors. In some areas with very low light, I see visual issues like this: It almost appears to be green in hue and I assume this sometimes happens in low light areas. It's pretty hard to see but definitely noticeable. Is there a term for this effect? Is there any way to mitigate it?
Well this is embarrassing. I can't see it in the pictures this morning. It's definitely my Mac's night time color adjustment.
