For spring 2012, "it's all about using nail color as a fashion accessory," says Jan Arnold, founder of CND. And according to Glamour magazine's February 2012 issue, the hue of the moment is Carrot orange, like CND Colour in Electric Orange.

To intensify this shade, nail pros mixed white and yellow polish right into the bottle. But the easier way is to start with an opaque white polish and then top it with a bright shade to give clients' nails an instant pop.

Glamour also suggests pairing bold eye makeup with even brighter nails.
