hey man it makes sense that but its only when i wipe other colours over each other, say pale blue, and mainly white...my blacks get a hazy glaze over them making them appear like a dark grey, which points me to overworked skin cos the other colours should just wipe off and not leave any trace, sucks so bad.

and yeah allot good fresh pieces lack contrast once healed, see it everywhere, sadly i don't always get to see healed pieces which is why its so important i try figure this out.
