As it's a pretty warm beige I would personally opt for a dirty blue or green. Both bring out the undertone of the beige in a slightly different way. The dirty blue makes the walls look more yellow and could give the room a beachy appeal, while the green doesn't have as strong of a contrast with the beige gives more of a country vibe.

The alternate philosophy is to match your warm beige with a warm feature, which seems to have been the intent of the chartreuse, but I would have chosen a brown or a red

I've guestimated some shades here and included very roughly done photoshop snips. Gives you a starting point but you won't really know what it will look like until you have a go with some sample pots

Of all colours suggested, my favourite is celerygirl's last one. The only hesitation is I don't know how it will match up w/your current wall colour of beige. Think it looks stunning with white walls. I repainted my adult sons' bedroom feature wall this colour several years ago & it was dramatic and moody.

Paul, this is a second posting, still can't decide, some more great ideas above, annb navy would look lovely with your beige walls, cipriano's colour choice are also lovely, from memory this is in a warm climate?

@siriuskey Melbourne to be precise

Love those two wallpapered feature walls, LesleyH!

@LesleyH would it work with beige on other walls?

One more inspiration

I love the navy / dark blue grey look! Otherwise I'm loving olive at the moment, similar to Cipriano's 2nd photo. Maybe order some brushoff sheets from Dulux e.g. Burnt Fig, Ceylonese, Leadman ... or Haymes have great earthy colour range too.

You can borrow wallpaper books from suppliers and compare some you like by holding the samples up to your walls. Be sure to test how well they complement each other at different times of the day under different light conditions. I know it's hard to know for absolute certain how a particular wallpaper pattern will look on a large scale, but it's a place to start. And the people at the decorator stores will be happy to advise you.

Wow, that's really gorgeous, LesleyH! Enjoy your stay!

Lovely part of the world leslyh, did you pick your art prize yet?

There's a Houzz story that featured yesterday; it's worth reading as it relates.

Me too lesley , I need to spend more time, I'am after something large at the moment but that could change, I'll let you know.

I am blown away with how clever people are! Their ability even to change the colours in the photo is just so clever, I'm going to call upon people to help me when I'm ready to update our kitchen and one really tiny bathroom soon. Just got to take photo's and hope I get the same assistance from you clever people.
