Dulux natural white is a nice white that isnt too stark. I avoid using a version of the wall colour, it limits your future choices.

@bigreader - I'm curious as to why you would avoid using a version of the wall colour on the trim (this is not in any way a criticism of your comment - I'd just like to understand it better - I've always had matching walls and trim but perhaps that's my lack of imagination).

thank you. I was thinking of the natural white.

I'm doing white trims with white walls and white ceiling and doing three versions of the same colour so I know they all sit harmoniously together. It's all personal choice really. Just make sure you know the base of your whites, or they can clash terribly!! Thus why I stick with the same in different strengths!

@jmm1837. :) I learnt a lesson when we painted dad's house Dulux sandy day with 1/4 strength on trims. He hated the colour on the walls but with the matching trims, the only wall option was a weaker Sandy Day.

My last two houses have had wood stained trim or a version of Dulux White. It means I can change the wall colour without repainting the trims. I can get a lot of years out of stained trim without doing anything to it but love being able to freshen or change the wall on a whim. However my partner may not think that's so great (he's rolling the living walls as I type).
