There are a lot of factors to take into consideration before trying a new hair colour: maintenance, how easy it is to achieve with your natural colour, and how it'll look with your skin tone are all common ones, but one thing you might forget to account for is your eye colour. Your eyes can be used as a secret key to what colours will be the most flattering on you.

Looking at the colour of a person's eyes — whether they're green eyes, brown eyes, or blue eyes — when recommending a new hair colour is something professional hairstylists do all the time, and ahead, three experts are sharing their wisdom with us. But first, let's clear something up: this is not to say you have to stick to the recommended list of hues just because it's what complements your eyes. Look at this information as another tool to keep in your toolbox if you're ever feeling stumped on what direction to take your look next.

"People with blue eyes have quite a few options for hair colours that can make them stand out," Laura Gibson, Rusk's artistic director, tells POPSUGAR. Hitomi Ikeda, master colourist at Rob Peetoom salon, adds: " When you have a blue eye colour, you can pretty much rock with any shade of blonde and brown hair. "Blonde is one of the most common hair colours for people with blue eyes, and it looks great because it's a natural-looking combo. Just look at celebrities like Gigi Hadid, Taylor Swift, and Jasmine Sanders. But the list of flattering color options doesn't stop there.

Matt Swinney, Rusk's global creative director, adds: "The hair colours that typically look best with blue eyes are platinum blondes, sandy blondes, strawberry blondes, ginger reds, auburns, espresso browns, and raven blacks." These colours all give you the "perfect amount of contrast to make blue eyes pop," Ikeda says. Celebrity examples include Alexandra Daddario, Emma Stone, and Megan Fox, to name a few.

For even more clarity on the most flattering hair colour for you, Swinney recommends you take a peek in your wardrobe. "What colours do you like and feel the best in? Then go to that family of hair colour, and you will be feeling your best on the daily," he says. That information, combined with your skin tone, will lead you to your perfect match. "For example, if you have very pale skin, a soft copper or platinum would pair better with your skin and eye combo," Gibson says. "For those with darker and more olive complexions, a dark espresso brown will really make your eyes pop and your skin glow."

Ikeda emphasises how important it is that you "choose a shade that won't clash your skin complexion," adding, "I always recommend scheduling a consultation with your colourist in person to ensure your achieving your desired result."
