Why not use some of her art work on the walls, in different size and style frames (natural, black, white & silver) - you can pick up some cheap frames in the op shop and the bargain stores - just buy some spray paint, and have fun - let your artist help....... you can even photograph some of her art work and have it blown up to poster size - the brighter the better. I'd suggest painting the walls white, with maybe a feature wall a timber bed head - one with a book shelf would be great - a double of course - the room is big enough. A rug to anchor the bed and some funky cushions. An Eames DSW white retro chair and a small white desk with some floating white shelves for odds and ends.... I'd probably get a white roller blind for the window, and paint the door, wardrobe doors and skirtings white, and a lovely large retro style light fitting in the middle of the room, or a hanging pendant next to the bed. A small bedside table - try Ikea - they have a great range, and not too expensive, you may even be able to get a great bedhead there - she sounds a very practical girl, so no frills. You want a young, fresh, modern look. Place the artwork randomly, in groups, on the walls - hang paper cut outs on the walls with blue tack, to see the effect, before you put up the art - Your artist could help with that too. What's her favourite colour??? Does she have any hobbies?? We need photos and more info.... What a lovely step dad you are!!! Good luck. I hope I've helped...

Hi, I like the overall concept of the darkish grey, it suits the home. I am a colour consultant and have been working with the Dulux range for 17 years and you are on the right track with the Guild Grey. The Dulux Signature will give you a dark blue house. Another option if Simone Weil which is just a bit lighter than the Guild Grey, if you find that one too dark. Sample pots and A4 brush outs onto white cardboard are the best way to decide, because computer programs give an overall impression of the "look" but are not accurate with colour choices, you can't beat the human eye. All the best, it's going to look great.

The visual artist needs the window - so position easel? or other working items where the keyboards currently are . . . and start working from there. The blue sofa cushions - maybe hang them against the walls (they could function as pinboards?) - but I think you need something to deaden the sound - or your neighbours may hate you. Rugs on the floor and the thickest drapes you can afford (or improvise with blankets) for the window. Hmmm . . . maybe artist towards the right-handside (door-side) of the window - trestles in L shape along the long wall, and a bit of the window to make 2 desks - and musician's stuff occupying the wall adjacent to the door and into the centre of the room? Everyone gets a shelf each in the cupboard . . . and a dedicated space in the room?

Oh. Heck this person is not being helped. I agree to not put such a shocking colour on such a huge surfaces, that turquoise would cost a lot of money on permanent fixtures. We need to choose something we can live with a long time and when we want to add vibrant colours choose something as an accessory, like saucepans, or display on shelves. This can be later changed. Have a look at displays or setting in say IKEA at least. Or Domo if there is one in your city. Interior space is what you see every day, every wake up moment and you can get quite sick of it with such a strong colour. Aim for sophistication, easy living. If you are not confident get some pro advice. It is cheaper in the long run.
