to suancol......a 'yellow/pink based beige'? Having trouble trying to get my head around that colour and 'seeing' it in my mind's eye, suancol! If one had to mix it up....could it also be described as a...pinky beige with some yellow in it... or a yellowy beige with some pink in it? Or is it a pre-mixed colour that can be bought off the shelf so has an actual brand name? I'm very curious! From what I've learnt about colour..and what comes from mixing this with that...I've learnt that BEIGE, like GREY, is one of those indefinite hues that can be a combination of several colours.,,,its not a colour in itself... I was looking at a designr's page where many of the bedrooms featured were in Grey and I was surprised that I really liked some of them...so serene and pearly soft....then it dawned on me, Photography combined with Photoshopping is very clever today. I bet if I painted a my bedroom exactly in those grey colours it would resemble a tomb...probably because of the amount or quality of light coming into the room. So not a fan of grey for interior decor, nor a fan of beige...whatever hue these are. Not crazy about all white interiors either where the colour interest comes from..."pops" of this or that.

Great colour choices! I agree to go with the grey rug, but you can use the yellow as a subtle highlight colour in the design. Here is a photo of our Clover rug in grey and cream , but you could easily make the cream a light yellow. At Tsar we custom make rugs to the exact right size and colour combination to ensure you get it 100% right. Have a look at tsar.com.au. We'd be happy to assist.

You have a lot going on texture-wise so I'd probably keep it simple in terms of rug texture or there'll be too much going on at once. Warm would do well in this room though, so that's good! You mention it's away from the light outdoor area, is this photo an accurate representation of the lighting you normally get in this room? So in summary, you might want to have a look at rugs that don't have much texture, and are a bit brighter in colour to help brighten up the room. Below are just a couple of examples of rugs that could work, and one more neutral example.

I have two dark grey sofas and I am eager to lose them as I can't find anything too complementary for the either! They seemed like a good neutral tone at the time but being dark they have showed up lots of stains (young kids). Your question was cut off but if you wanted to add a rug or furniture, I might suggest an orange/rust tone or even a red? But the colours of your walls will have a big impact... Hope this helps. :)
