Well, when I tried LPV? it was the walls who had difefernt coulours thus when the TOD changed the colour of the walls changed mixing the diffused lights cast on them. The Balls in VXGI were emissive balls meaning they were the light sources. Does that mean, the diffused lights on walls from light emissive sources don’t mix up while if I try the same case as in LPV where the walls were painted in some coulours then teh mix will happen like in paint? Or is VXGI diffeernt than LPV and more accurate?

I think VXGI and LPV should behave similarly… but the experiments that you describe are different. In the balls case, it looks like the light from the balls is mixed on a white wall. In the screenshot with boxes and daylight, it looks like a yellow box is illuminated by direct and reflected sunlight. The incident color is multiplied by surface albedo color, which is not white, so the output color is different.

Specifically, on picture 2 of set (://imgur/a/VGQnS), the floor reflects cyan (00ffff, well almost) and that cyan is multiplied by yellow albedo of the box (ffff00), which gives green (00ff00). On the third picture, red light from the floor (ff0000) is multiplied by yellow (ffff00) and that gives red (ff0000).
