In my photographic work I've often desaturated the blue tint that appears in the highlights on red wine bottles but now creating them in Blender I'm finding the subtle tint adds a great level of realism. If you image search on the net for red wine bottles you'll see all the slicks/highlights on the glass have a tiny tint of blue to them.
Does anyone know how I can achieve this in Cycles? I can do it in LuxCore (reflection colour is part of the glass material) but I'd like to stick to Cycles if it's possible!
Secondly, does anyone have any idea why this actually happens? Green glass, white light, blue tint!
