Rather than feeling restricted by 'rules' when choosing a nail polish shade for your skin tone, Marie says you can find out your skin undertone to help you narrow down shades you'll love wearing.
"Your skin is either going to be cool, warm or neutral. Cool will appear more blue, warm will appear more yellow. Look to the colour of your veins to help determine your undertone," she told me.
Blue veins = Neutral undertone (will enjoy most neutral shades).
Green veins = Warm undertone (will enjoy warmer neutral shades).
Purple(ish) veins = Cool undertone (will enjoy cooler neutral shades).
She also has another great tip:
"Look at your nail beds (the main middle bit of your nail) with no nail polish on in natural lighting. Those with pinky/red/purply nail beds are more likely to have a cool undertone. Peachier nail beds are often more visible on warmer skin undertones."
My Favourite Neutral Nail Polish.
Marie has been legendary enough to compile a list of the best neutral shades to suit each skin undertone, but first, I thought I'd share two nail polishes I've found work with my skin's olive tone and warm undertone.
1. O.P.I Samoan Sand.
I get so many compliments and questions on this nail polish shade. It's no surprise it's one of the brand's best-selling colours.
OPI Nail Lacquer Samoan Sand is one of the best neutral nail polish colours for olive skin tones. I love it because it's more of a beige-y neutral that I find really suits my skin tone, as opposed to a lot of popular pink ones.
But the best bit? It does not chip. Well, nail polish chipping is as unavoidable as paying your taxes, but I find this polish lasts well for an at-home manicure.
Here is a picture of how Samoan Sand lasts a week and a half after applying, surviving housework and multiple trips to the dog park. Pretty good, eh?
Because Samoan Sand is quite a sheer polish, I like to apply two coats. It has a very subtle pearlescent sheen in the light, and like all O.P.I nail polishes, is free from harmful chemicals formaldehyde, DBP (dibutyl phthalate) and toluene.
