I really like the way Larian implemented darkvision, but then I'm also one of those with the silly notion that a D&D game should be based on D&D.
To me it's very far from what actual D&D states: That you can't discern colour in darkness with darkvision. Currently it feels like I'm carrying a bright bluish hued light with me, and I can still see colours perfectly fine (just with a cool blue tinge).
