With so many new lipstick trends and products to try (like the red orange that鈥檚 taking over the red carpet or Jouer鈥檚 Papaye lip gloss that鈥檚 blowing up Pinterest), picking just one can be a real challenge. Plus, that shade of red that looks so good on your BFF can sometimes be all wrong when you try it on.

Blake Lively always seems to get it just right, and there鈥檚 pretty good reason for that: Her makeup artist Kristofer Buckle has a nifty trick for always choosing the right shade.

The celebrity makeup artist, who also works with Kelly Ripa and Kate Beckinsale, spilled the beans to E! that he keeps two things in mind: his client鈥檚 skin tone and where he wants to draw focus most.

For skin tone, Buckle advises to avoid getting too matchy-matchy. 鈥淚 usually like to pick a color that has the opposite undertones than the complexion so it looks fresh and not muddy,鈥 he says. Case in point? 鈥淚f someone has a lot of yellow in their skin, I use a pink with cool undertones.鈥

As for whether to go bold or keep things more muted, it all depends on the rest of look. 鈥淚 select a lip color to either pop, recede, or balance,鈥 he shares. 鈥淚f we鈥檙e going for more of an eye look, I select a flattering color that isn鈥檛 too deep or distracting. If we go with less on the eye, I鈥檒l select a bright or deep shade lip.鈥 Makes sense, right?

For the in-between days, Buckle plays it safe and keeps things neutral. 鈥淪ometimes I select a color in between when a natural, balanced look is desired,鈥 he says. Naturally, he likes those in his own Kristofer Buckle Cashmere Slip Longwear Lipstick Duo ($33) line best.

Once he鈥檚 got the right lippie color, Buckle gets to work with liner to make sure things stay in place. He then finishes things off with another coat of the chosen color.

And, voil脿! Picture perfect pouts, every time.
