Color correction or brightness?

I don’t know if its a color correction bug or what, with H2A colors it’s weird. When i go to put Sage on, it looks Sage but in game it looks Olive. How come? Is it my brightness? The lighting in the maps? Or a bug? Can someone help, because I’ve been wanting to recreate a Myth pic from 1999.

Could it perhaps have something to do with your HDR settings? Not sure if you are using an HDR display, but that may be the thing that solves your problem. Also, does the color appear olive on all maps? Certain maps sometimes show the same color as a different shade.
