Warm or cool walls?

[Elizabeththefirst]

Greys and mutes are very fashionable now, right? I think I prefer a warmer colour palette...how could I make this look stylish?

Warm grey? There are all sorts of greys with different undertones. Or a warm duck egg blue? Or a pale olive / avocado? It depends on the rest of your decor and what overall look you want.
