OSB board will do the trick. You need another photo for us to offer a species and finish. Natural finish (clear coat...water based polyurethane finish...NO oil modified) in a low gloss or satin finish on white oak with FLOOD LIGHTS will offer the same "look" as the poor photo. Beyond that, you will need a better photo.

It has a descent lighting. I like bold colors. and this is a living room still in construction. The room has rectangular shape, this is half of the room. There is window on the opposite side of the TV(my back side while taking the above picture). The window size is 6 x 4 feet.

do the blue on only one wall,contrast it with white ....use blue hardware and small motif prints

Hi there - I think if you are able to post any photographs at all with your question, you will have loads more helpful suggestions. People around here are just so visual! 🌈👍
