Keep all your internal doors and door trims white if your skirtings and walls are white as mentioned.

If you are aiming for the Scandi look, steer away from any timbers that have a red tone. You may wish to consider a charcoal or black wood wash over the Meranti to maintain some relevance to the Scandi look - best to test this on a sample before addressing the door - Good luck!

Add colour to your room with accessories, then You can change the look whenever you feel like it, without having to paint the walls.

Agree with Deanne - consistency as always is the best option Frames typically/traditionally will be all the same colour, and if you want to pick out the door differently in a bold colour then go for it, but keep the frames the same and it won't look out of place. I'd also also consider lightening/freshening up the flanking inset panelling too. I also wouldn't be scared of painting the entire door black to make more confident design statement. Best to own it one way or the other. Good luck :) PD www.pauldistefanodesign.com
