Photos of the exterior would be helpful.

the first is close to the true colour of the wall paint. second picture shows the colour as dark but it is not at all that dark.

Vijay, 1243 as a base with couple of stripes 8754 should look good here. Just a couple of feedback based on the pics. The headboard should be wider it should touch your lower back while sitting on the mattress. Are we not planning for a fan , don't see a provision. The False ceiling is not in water level it is arched in centre , please recheck. Also recheck if the loft door touches the false ceiling, from the image angle it looks like a close call. We may have tough time planning the curtain on the window. There is no provision made for that. Thanks, Nitin Cornerstone Designs, Bangalore.

do you have the interior designing and finishes finalized? as I mentioned earlier, everything in the room has to be tied together. I cannot give you a colour for the arch if it is going to clash with the window frame job, or the cabinets or the wood. In case you don't, I can help you with that. we offer consulting services, which is basically this, the help on Houzz, in a lot more detail.
