Plaster dried or not

[Lochside]

Hi please help me. It’s been 8 days since i had my room reskimmed. He first bonded the chased electrics then next day skimmed over with 2 coats of multifinish using pva beforehand . One side is salmon pink so i know it’s dried . But the other 3 sides still look dark pink? A socket was plastered over by mistake so electrician will come out to fix it . But The plasterer came out today and said it’s dry the walls and that i could leave heater on low to take out moisture if i feel it’s not . When i look in diff light the side walls look light pink but the other 3 walls look nothing like salmon pink . I’ll wait another week but really need to move back in the main room . What do you guys think? Tia

pictures attached

This is a north facing bedroom too the theres not much light coming through . But plaster should be a lighter colour or is it the light making it look darker ?

what you guys think

The bottom right picture looks very dark and I would say not dry. It wouldn't stay that dark no matter what the light was like. Some of the others look a but patchy. Personally I would wait a bit longer. It's quite damp and cold at the moment so would take longer than during summer unless you've had the heating on a lot?
I can't speak from experience because we waited much longer

That’s what i was thinking it can’t be dark and dry . I’ll attach pics the day he plastered it . Was deffo wet and chocolate walls then x
