dying fabric

[sugarcoatedlie.livejournal.com]

I have a question about dying fabrics. I upgraded to a new larger sized bed recently, and a friend gave me all her old bed linens. It's a bunch of high quality, expensive stuff, that was very gently used and still in fantastic shape, and I'd like to use them since all I can afford for myself is the cheapy scratchy sheets. The problem is that my bedroom is a deep raspberry pink with dark woods and orange and red accents, kind of an indian sari influenced color scheme. And most of the sheet sets and duvet covers are very pale celery greens and totally clash with my decor.

I figured I could just dye them darker since they're so light colored, but I've honestly never dyed anything before, and I'd be a little bummed if I ruined such nice stuff because I was being picky about color. They're all just high thread count cotton sheets, so I should be able to dye then with RIT dye or something right? Any suggestions would be appreciated because I've got about 5 complete sets, and NONE of them match my room at all.

EDIT: I should add that I'm a graphic designer and already know lots about color theory, so I'm not so worried about trying to make green into orange and ending up with something terrible. I figured I might try a dark pink or burgundy on the lighter fabrics, and a dark chocolate brown on the darker green ones. I mostly just need to know if fabric dye will work for this type of thing, and any pointers on how to use it and things like that. The color part, I've got. :)
