Ok, I’ll go serious. If there’s one advantage to magnolia, at least it covers easily enough.
Greys & greyish blues are very popular at the moment and look really good with white woodwork – you’ll probably have to spruce your skirtings and architraves up if you give the walls a fresh coat. Personally, I’d stick with white for woodwork, but maybe eggshell instead of gloss.
If you’re doing it yourself, avoid anything too dark, you need bloody good paint and a skilled decorator to get a good finish with a dark paint.
As far as good paint is concerned, we used Fired Earth for our downstairs – but that’s ok, because the rooms aren’t massive so the expense, over say, Dulux or Jonhnstones was worth it. Our decorator who was really good said she was impressed with it anyway.
