Which room is this? And what sort of look are you going for?

Some of the sticker murals you can get these days look great and there is a wide range available. I think many of them are removable so you could change it when you want a new look. A quick search on eBay will give you an idea for what's out there.

I slightly see what you mean about the paint/floor combo but it doesn't jump out at me as being a problem. Perhaps a warmer shade on the wall would look better with the floor though.

Here are some I like...

@Loobyguru It's the main bedroom. Thanks for the idea, I thought those were only on wallpaper. Since those are removable, I may consider using them with black wall shelves, I've seen a few I like on eBay. I'd love to change the color on the walls although the same color scheme is painted throughout my house. The floorboards were installed first before the house was painted.

If you have a standard lamp somewhere around the house, it might be worth popping it in that corner between the window and the mirror to see if you like the look of that. It would just fill the corner without intruding into the room, and be a softer light for when you're winding down too.

Another thing to consider is your window dressing - curtains are more cosy for a bedroom and there are a lot of companies offering inexpensive ones online that look great. You could keep your existing blinds as well to cut out more light.

My own bedroom was a similar colour when I bought my house. Personally I found it quite unwelcoming, although I think it was just too modern for my ancient home and in your modern home it looks much better. A great halfway option if you don't feel up to painting it all, is to choose a stronger or brighter colour just for one wall.

The colours aren't quite right, if my monitor is correct, but they aren't horrible. Your walls should have more pink undertones, rather than yellow, to truly match the floor. But, honestly, I think you should completely decorate and then see what you think.

Do you have enough storage in your main bedroom? If not, I would put a large chest of drawers and then that same mirror hung horizontally above it, with a vase, or other couple of small, colourful pieces on it.

If storage isn't an issue, a large fabric ottoman with the mirror horizontal would be nice and add warmth.

Make either the drawers or the ottoman centred on the wall when the door is closed but obviously they can't be so large you can't open the door. That will give the wall harmony.

If that is the wall you are staring at every night from bed, ditch the mirror and find a really nice piece of art that you will love to look at just before you nod off.

@loobyguru yes it's a modern home. Would you recommend having a lighter floorboard? Also that's what the rest of my room looks like.

@boundsgreener yeh I have a lot of storage and I may need to move the mirror when I have a set idea of what to do. The ottoman is a great idea. Thanks.

I agree an ottoman or a chair would be good in the corner - as well as solving the empty corner, it's somewhere to sit while you put your socks on!

It's much easier and cheaper to give the room a lick of paint than to replace the flooring, and less permanent too so you can redo it if you don't like the first attempt. Unless the floor offends you on a daily basis, or you are made of money, I'd work with what you've got.

White wash your floorboards

One simple trick before painting is to turn the mirror lengthways. That way it will stretch the mirror to fit the wall. Then you can think about colours.

The floor and the wall paint are fine. Wood floors go with everything, and you're the only one who will notice. If you want to change the color, go with something more beigy, but honestly, it looks fine.

Hi nice sideboard with large mirror on the wall
