Gamma? sRGB? Don't know the terms, but my colors are weeeeeeird.

Thanks for the replies and elaborations, guys. Glad to hear I’m not the only one that has had the problem. It sadly doesn’t sound like there is a way to simply disable it - your suggestions all say to work around it. I’m aware that there is an sRGB checkbox and that I can tweak the gradients, but I was hoping there was a way not having to do any of that at all. My background is in Photoshop, so I’m used to a more “what you see is what you get” approach. I’m sure there are good reasons for things working like they do in UE, this approach just seem incredibly counterproductive to me so far, and seems like the kind of thing you’d want a way to potentially disable or toggle off.
