You need a grey lipstick. It may seem like a bold statement, but its true! If you enjoy mixing your own customer lip colors, a grey lipstick is o hand for giving any shade a cooler, more pastel edge. Personally, I prefer to use a neutral grey like NYX Black Sesame Macaron Lippie ($6), but cooler toned greys will provide an even stronger effect. Click through for a couple examples.
All of the lip mixes below show a 80/20 ratio in favor of the base color.
Grey lipsticks give bubblegum pinks like MAC's Viva Glam Gaga a lilac edge.
Grey lipsticks will tone down strong berry shades like Maybelline's Berry Ready.
Mixing grey into a deep red like Revlon's Red Velvet will create an interesting brickish pink color.
Combining grey lipstick with a cool medium pink shade like Mirabella's Posy will make a medium mauve tone.
Mixing your own lip colors is a fun way to experiment with shades you wouldn't usually wear. Grey lipsticks aren't particularly common, or very easy to pull off, but they definitely have a place in your collection! I hope this post gave you some ideas!
