What colour area rug


I need a rug to run from behind my sitting position up to where my speakers are. I wanted to have my hardwood floor visible from the front wall to where I put my feet up. My room gets a ton of natural light, my whole left wall has a window that runs along 2/3 of the wall  and my room is painted eggshell white. Currently I have a shaggy cotton rug that's black and seems to suck in a lot of light

also any ideas what material rug to get? Cotton? Wool? Shag or no shag?

For best sound walls should be blue 🧢and the ceiling should be green 🐸. Been there, done that. I’m not hot doggin ya! 🌭Oft times no rug at all sounds better than a rug or carpet. It all depends. Proceed with caution. 
Don't get Berber. Hard to clean. A well made nylon rug will suffice. Choose a favorite color that goes well with your furniture. Keep in mind that dark colors will show every piece of lint and other things that are not noticable with lighter colors.
