Negative feelings seem to have cornered the market on color metaphors.

Seeing red. Green with envy. And don’t forget feeling blue.

Jewelry line BYLU (pronounced like the color) just may change its namesake’s image. In fact, it’s reclaiming all the colors of the rainbow for happier thoughts. The spring 2005 collection features thin fourteen-karat-gold strands interlaced with small garnets, emeralds, pink tourmalines, and other stones. Last year’s spring line is more eclectic: chunky lapis-and-turquoise necklaces and streamlined silver earrings.

But the most impressive, the Evening collection, mixes a classic feel with bold colors. Diamond-set petals cradle large turquoise, coral, or onyx stones to make dramatic, showstopping rings.

It’s enough to leave you tickled pink.
