Horwath
Legend
Now darkvision turns darkness into dim light at given range.
dim light only has penalty(disadvantage) to sight based perception.
What if that penalty broadens up to anything relying on sight that isn't attack roll?
I.E:
Investigation; you need to see fine details
Insight; black and white vision and low detail, you might miss some body language clues,
Thief tools; again, fine details matter here
Most of artisan tools;
Possible stealth on the move; you could miss some clutter on the floor due to poor vision. Some Perception check(with disadvantage) might negate this.
Survival; foraging, some poisonous berries might slip in with edibles due to color.
