I’m moving into college in a couple of weeks and need to find a dark teal bedspread/comforter/duvet cover or whatever 
My roommate’s is this http://www.ikea.com/us/en/catalog/products/00080214 in the red-orange.
Most importantly, I want a solid color.
Peppermint has a great idea. I would suggest the sheets also. Or go to a fabric store and do the same thing. I like a fabric store or sheets. You can get what you want. On the fold of the duvet, you could use some large buttons, any kind of trim to dress it up.
If you are unable to find the colour you desire in any of the close bedding stores or large plaza malls, just go to the bedding section of a large store that has beddings and either sew yourself or get someone to make a duvet cover for you. Very easy project. Sew the two sheets together leaving an end open or the middle of the back slit and open. Add a zipper or velcro and there you have your duvet cover
