Here are some Houzz photos that I like:

Another option is to paint the ceiling:

Look forward to hearing from you!

Some photos of the room would be really useful.

OK, I will try to send a photo when I can. It is an empty white box with a window and a couple of doors (one to ensuite) right now LOL... i.e. complete blank canvas, has recently been added on and has just been plastered and has base of pure brilliant white all over. Flooring will be carpet but I haven't chosen that yet! :-)

this is what my bed looks like:

Photos would help but in the mean time...I would be tempted to go for it and paint all walls and woodwork the same dark navy - then use lots of white, paler neutrals and textures to break it up and a large mirror or mirrors to reflect light around...it also depends how you want your bedroom to feel - dark bedrooms can feel very cosy if you get all the elements right. How high is your ceiling? I would only recommend painting just the ceiling dark if it was very high - as in a period property (the dark colour would make it feel lower)

If it’s south facing and doesn’t get much light it would be useful if when you take photos you make sure you include the window.
I’ve got a particularly light bedroom and just painted it darkest purple but with white textured bedding and a splash of accent colours it looks good. Also got a dark north facing bedroom and painted that very dark except where the bed is and when finished I’m sure that too will look good. However I’ve gone dark in bedrooms before with less success, and I don’t know why it works or doesn’t. So the guys good at colour could do with as much info about your particular room as possible to help you get it right. :)

Hi Agata, I like your colour scheme. I would personally paint dark blue on the walls and will use light wood or laminate for the floor since it is the floor that reflect the lights. If you balance well the dark colour on the wall with white or bronze accessories your room might look brighter (see photos below). I would also place many lamps as possible to up the room when needed.

I think your choice of colours is excellent, the metallic accents keep a dark room from gloominess because they sparkle and the white makes individual pieces stand out. Did you ever watch the film 'Tron'? As long s you keep that film in mind, the darkness and outlines made of light, a dark room will never look boring or depressing, but cosy and exciting. Good luck!

Thank you so much everyone, very helpful responses! I love your 2 images colourhappy... I do like textures such as sisal!

I have just got some photos... and looking at the room again I realise the lighting is not too bad really... it is just that the rest of our home is very light and sunny compared to that little corner :-) Ceiling is not high. The room is 3m x 3.7m.

colourhappy your suggestion of warm grey with the blue really appeals to me..

I also love the freshness of green against dark blues and I am thinking of including something like this art or a cushion as well as a fresh plant or 2 :-)

These colours all work together, especially with a deep blue with a green undertone like Inchyra Blue. I would paint the wall behind the bed first to see if that is enough. Like these images:

With blue I would make sure there is plenty of brown to balance it.

All those beautiful blue bedroom photos are making me want to paint over my white bedroom...I say go for it.

That's great ... lovely pics I've again colourhappy
My next question is how should I dress the window? Curtains? Roman blinds? Venetian blinds? shutters? as you can see the neighbors fence is quite near so no view to show off... If it makes any difference this is a guest bedroom.

I would build things up in increments as every time you add something it changes the overall look. Get the walls sorted and have in mind the flooring, then when all that is working think about the blinds. Looking at the images above they are quite small rooms and as they have lots of texture going on the colour is dark and desaturated. I wouldn't go too bright if you want texture, keep the palette limited.

I think that a dark color on the wall helps frame white furniture, door, curtains and picture frames.
I agree that flat surfaces will reflect light but I don’t think much floor will be visible so suggest light bedding.
Since part of the issue is the neighbors fence perhaps you could stain that a pale colour to help reflect light.

How about grey tinted mirrors in rose-gold frames?

You can try with one accent wall.

Thank you so much for the inspiration... I now have some tester pots and will be painting one wall to start with.

Did you make a decision

Agatha, just noticed your lovely 'panelled' doors.

What colour are they painted? Nice.

I have found some nice dark blues, but some other extension 'issues' cropped up so this little room has been left for a bit :l
Thanks E D, those doors have just been fitted and are as they came from the supplier...I am really pleased with the style. They came coated in a primer :-) We were going to paint them white when we get round to it!
