I like brown for you, but not dark. Think coffee with cream. As for the mural, it depends on your artistic abilities. Maybe something here will spark your interest:

Good luck!

Grey and brown camo, has a black trim around it, and some white to it too, and (cover your floor for this one). Stand back with a red paint ball,

and shoot it in the center of one wall. A green army blanket. White sheets, big red square toss pillow. Brown furniture. Do this over a desk, with a TV on it, and the red target background.

Also don't forget to search this on Google.

Im 14 and I'm changing my room. I need paint ideas my room is light blue so i don't want that any more. I think i want a grey and red wall or just to paint the room brown, idk i need ideas with what colors will look good and what i should paint for my mural. Btw I'm a guy.
