As a September baby, I'm partial to all things autumn. School supply shopping, football, coats that are warm but not too warm. And, of course, fall colors. Browns, warm reds, deep greens, gold ... you know the drill. And as pretty as those hues are on tree branches (and, let's be honest, leaf piles in the street), they also look great at the tips of fingers and toes.

I'm talking about nail polish, one of my favorite ways to change up a look fairly quickly without too much work. (I know, I know, it does take a steady hand a few tools to achieve a smudge-free DIY manicure, but I promise it's worth it!) While color choice is definitely a major factor when it comes to polish, even more important is to make sure you're using a safe, 5-free brand.

Not sure what 5-free is? Well, in short, it means that the nail lacquer is without five major chemicals often found in conventional brands: formaldehyde, dibutyl phthalate, toluene, camphor and formaldehyde resin, all potentially dangerous ingredients that could disrupt your endocrine system and even cause cancer.

So here are the nine colors you should try out on your nails this season, all from healthy, 5-free brands. While the price points may be a little higher than your average drugstore brand, you're paying for healthy, chemical-free lacquer (and they're still cheaper than an average salon manicure!). Happy polishing!
