I would inject a bit of colour here perhaps choose the lighter mauve/pink colour which will work well with the copper lighting.

Agree would find a fabric that combines the colours you have chosen then pick out some of the colours from that fabric and use them in cushions.

Definitely go brave & inject some colour. The idea of combining your chosen colour palette is good and I would particularly love to see some copper detail if you can find a fabric that you like. This isn't a purple fabric but gives the idea (though the red could be equally striking). I hope you find something you like! http://www.johnlewis.com/john-lewis-talis-diamond-furnishing-fabric-red/p3136029

I would keep the blinds plain! I like the 5th colour (left to right) in a velvet for texture and warmth. I would then pick out jazzy cushions in different sizes incorporating the copper and the blind colour and greys, taupes etc. These can be changed any time at much less expense than the blinds. Good luck!x

The blinds need to be patterned and incorporate several colours to blend and to contrast with the rest. I'd definitely include a strong colour otherwise it will all feel a bit bland. And I'd draw in the colour of the lampshade which I love. Take a risk - the room needs something to bring it to life. Plants would help, too.

Gold, then when the sun shines and you need them partially down you will get a lovely glow to the room.

I'd get the 2nd from left pinky tweed ones. But I am mad.

if you do not want a printed fabric roman blind, consider making the blind more interesting, we would suggest the third fabric from the left with a 50mm border along the bottom edge of the blind. use the second fabric swatch from the left for the bordering fabric. it will look very smart!

from the left no:2

I would personally go for the aubergine velvet (thrid from right) with either a central 10cm wide horizontal stripe in the bronze silk (second from left) or with a 15cm wide band of the bronze silk at the bottom. - or both - just a thought!

It would lend colour and texture and you could repeat it on a couple of large cushions, then have a slightely smaller couple in augbergine and a slightly smaller still couple in the bronze silk.

Good luck!

p.s. on second thoughts I'm not sure I'd use velvet for blinds as can be a bit of a dust trap, but silks would be great as they would have a sheen like your lovely lamp shade. - try modelli fabrics.

You have several options that would work to suit your tastes. Grey is a neutral colour so any other colour would work with it. You could go for a bold colourful design to bring the room to life or something plain with a decorative trim or beading to add colour that way, perhaps incorporating the copper colour in the pendant light fitting.
