For those of you who believed that neon-bright nail polish would never become mainstream, here's some good news: it has. With ultra-trendy young stars like Rihanna and Beyoncé happily waving around their yellow-painted nails, it's no wonder that various cosmetics manufacturers are adding bright nuances of sunshine yellow and lively orange to their beauty lines and advertising them as the hottest trend on the market. With summer already here and the temperatures rising, yellow nail polish is one of the easiest style infusions you could add to your daily look.

Yellow is a bright, warm color with many positive and a few negative associations. Mostly, it's seen as symbolizing a good sense of humor, optimism and an overall lack of snobbery. It's a color that spells good fun and simplicity, the color of the sun, a fresh, summery dash of color in a world dominated by blacks and reds. Yellow nail polish will make you look friendly and unassuming in one glance - especially if you pair up this hot new trend with an outfit dominated by neutral colors to balance out the yellow.

The negative connotations of yellow include cowardice, greed and envy. However, you can easily make the others feel envious with your fresh, trendy look so never fear - if you're the friendly, outspoken type, yellow nail polish is your best friend for the days and nights. Two nice, affordable suggestions are Mode Cosmetics Nail Enamel in Couture ($3), which provides rich, creamy and glossy coverage, and Essie Hot Pop Yellow Nail Polish ($5.99), a chip-resistant sunny yellow option that will brighten up your day and your outfit. Shine on!
