I like second plan! That space will fit the wardrobe perfectly. Take all colors from the art. The colors can be lighter or darker than the colors you see in art. Take "Venice" with you to paint store and they might be able to help you choose good colors. Idea: paint four walls the same and see if you like that. If you feel the room lacks interest, then paint the accent wall. Choose a pale green that harmonizes with "Venice" and a darker green accent. Yellow + red accent White + blue accent

grey is a mature sophisticated colour. Complementary colours are shades of grey, black, dark blue and white. You can use yellow or red but very sparingly in soft furnishings. Some examples from the internet

HU, People are different with each one having their personal choices. IMHO, Yellow color is a very energetic and not so calming a color. It makes you active and excited (kind of leaning towards aggression). If you are looking for calmness you should try softer, cosy colors in the bedrooms. Thanks, Nitin Cornerstone Designs Bangalore.

Lighting plays a huge part in adding depth and warmth to a bedroom. I see that you have a light point just above your bed. Without too much expense you can create panelling up to the ceiling , run the wires behind it, and maybe and add a simple false ceiling along the length of that wall to install recessed lighting. A skilled carpenter can modify the head board and create a dramatic taller tufted headboard within the panelling Another option would be to paint the wall behind the bed and add a simple shelf above. Some recessed lights can be added to light up paintings on the wall just above the bed. The homeowners of the bedroom shown here already had a bed which they did not want to dispose of or modify. So all we did was to add painted pinewood box panelling up to 4 feet height, add a shallow display shelf on it, and add a simple shelf above with recessed lights
