Initially, the colors were greyish in the viewport aswell - after changing the color management settings in the render tab, the viewport is as it should be - but when I render it out, it remains with wrong colors. What am I missing here? Thanks in advance.
Edit: The slight tint of the image in general is due to f.lux. But the issue remains even if turned off.
Edit 2:
I already found out about color management settings that are set to filmic by default in 2.8+. In this specific case I've set it to raw as the texture input I'm rendering is in raw format, but for the albedo textures, I used standard, which still tints the render - not the viewport. The viewport was greyish before when the setting was on 'filmic' too. But changing the color management settings fixed that - but not the render.
This is what I'm trying to understand here, as the color management settings are part of the render tab, and I don't understand why the render tab changes my viewport, but not the render.
I found a quick fix by using "render viewport" instead of the normal render. But it's still awkward to not know what's going on.
