did you paint most of the yellow light in the editing phase? you shouldn’t do that, nine out of ten times in-engine lighting looks better because it actually fits. if you do insist on adding painted lights, be more careful with how you isolate it - if you look at the (our) left side ammo boxes, it’s clear to see how the yellow “bleeds” over onto the sky and other surroundings
as for the color, i would not recommend using flat yellow for gunfire effects, unless it’s a strictly stylistic choice, and even in that case it’s not bright enough in this shot to actually give off the impression of light. the soldier on the left for example looks like his face has merely changed color to yellow, rather than it being illuminated by something. a tint of orange always looks more pleasing to the eye, it feels more “right”.
