Is that a suede finish? Haven’t seen that for ages. Do you have any art or a rug that you want to use? Are the curtains staying? Is that the only bed linen you plan to use? What colour do you like?

Bigreader@ No it’s a paint, I want to keep this background colour like that and want to change the other sides colour in the room.

See this picture

Thank you @Foshan. I don’t to change background wall colour; instead want to add best to the rest of walls.

Ok many thanks, if I use the same colour; the room will look very dark.

As said by big reader...leave white or paint the same colour, without the brushed finish, on the other walls. You can not bring another colour in. There is enough colour already with the orange wood and the bed cover.
Also, the curtains look too small to pull right across your window correctly. They should be waved not flat when closed.

I would paint the white walls a soft but not too pale pink and add deeper pink curtains.

I think your idea sound best because the back wall has light chocolate colour and room lightning is not bright. I will try to upload entire room photos to see and also I would be much grateful if you can help me finding a right soft pink colour @Hi-925555113.
Thank you for your valuable idea.

If you want a brighter light then replace your old fan with a new Led light fan !

Thank you. My friend also suggests your same
idea. Thank you everyone. I will keep on posting once It got changed everything.
