This also happens to soul sand. any block that moves you down a pixel will turn you character darker and say the client light is 0

Should be closed as WAI.
This is not a bug since by the game's logic you're actually one block lower - it's just a side effect of how mud, snow layers, soul sand have a different hitbox and a different collision box (which can be seen in the provided screenshots - look at Y values)
