The notion of a single "best" liner shade for your eye colour is as outdated as eating for your blood type. But certain shades can intensify your natural eye colour and, in some cases, even change its appearance. Celebrity makeup artist Charlotte Tilbury offers her colour theories.

For Blue Eyes

"Contrasting shades bring out the eye colour, so copper and gold make blue eyes appear even bluer," says Tilbury. And when warm metallics pick up gold flashes in the iris, they really light up cool blue eyes. Dot just the inner corners, keep the liner tight to the lash line, or fill in the whole lid.

Other colours: Terra-cotta, champagne, navy

For Green Eyes

Red complements green on the colour wheel, so pick shades with reddish undertones. "Garnet, amethyst, and bronze are particularly dazzling on green eyes," she says. However, they can make you look tired, especially if diffused into pinkness. Lining the lid in black first helps.

Other colours: Rust, mahogany, aubergine

For Brown Eyes

You can’t go wrong with earthy browns, but "amber and midnight-blue tones emphasize the light flecks in brown eyes," says Tilbury. If you’re not ready to commit to too much colour, line just the waterlines. Rimming the eyes in dark blue gives the same effect as black in a less severe way.

Other colours: Mink gray, purple, cobalt

For Hazel Eyes

"Emerald and gold bring out the green tones in hazel eyes," she says, and warm, neutral browns enhance their richness. Diffuse a green line – or a chocolate-brown one, depending on how colourful you want to go – over the lid. Kick up the radiance with a touch of gold at the inner corner and the center of the lid.

Other colours: Bronze, olive, plum

And while we’re on the topic of eye makeup, here are a couple of quick tricks to make your baby blues looks bigger and brighter.

Line it
By now you probably know a couple of tricks to make your eyes look bigger. (Lining the inner rims with a beige pencil, for one.) Here’s a neat new one for faking big, round eyes.Instead of tracing your entire lash line to open up your eyes, use a long-wearing kohl pencil to trace only the center of your bottom lash line. Then use a cotton swab or your finger to smudge the liner, which takes the look from jarring to natural.

Highlight it
There’s a reason that even in #nofilter selfies, models seem incapable of taking a bad picture (and it’s not just their unfairly superhuman genes): They know how to find the light or at least fake it. A pearly eye shadow or highlighter dabbed on the centers of the lids, underneath the brow bones, and on the inner corners makes eyes look lifted and awake. Look for warm, rosy cream colors if your skin has pink undertones. Golden shades complement yellow and olive skin.
