Surely you know by now that eye-popping colors are the big trend for spring --

But you may be wondering which brights will work for you.

I think Smash star Katharine McPhee makes it pretty clear in this shot that turquoise is a great color on brunettes. Add some bright red lipstick and you're ready for a night on the town!

Want to see some McPhee-like options for turquoise dresses that won't put you in the poorhouse?

Read on!

If you're willing to splurge a little, your best bet is this Ralph Lauren matte jersey turquoise dress (Lord & Taylor, $124). It's perfect for your next big special occasions.

Watching your budget? This casual turquoise dress (6pm, $35.99) is inexpensive and flattering on a range of figures.

I'm personally nuts about this retro-style Tahari dress (Bluefly, $71.20). I could totally see Betty Draper in this dress!

Want to cover up those arms? Check out this super-sexy drape back dress (Guess, $158). It's perfect for your next date night ....

Okay, it's official. I'm going to be hunting down this color the next time I'm out shopping.
