Sounds to me like this is a great exercise in "letting go"!
Sounds like they didn't tell you what colors to pick....just start with colors you like (separately and together) and see what happens!
What's the worst that could happen? You'll have something to donate to charity when you're done, or find a friend who loves it.
What's the best that could happen? You'll have fun, learn something new (about quilting and/or about yourself), maybe even discover a new "flavor" in your taste for what goes with what!
I say just go for it...no worries, no regrets.
