Kylie Jenner has added yet another color to her Kylie Cosmetics lip kit collection. This time it's inspired by big sis Kourtney Kardashian, named Kourt K.

The youngest Jenner is keeping the lip kits coming after the success of the initial three colors, Dolce K, Candy K and True Brown K. The next few colors, however, appear to be named after a family member near and dear to the makeup enthusiast's heart.

Kourt K has yet to go on sale, but it's a dark purple that the Kylie Cosmetics team is "so excited for."

The eldest Kardashian sister wasn't the first family member to inspire a lip kit though. Jenner's big sister, Khloe, also has one. Koko K is a a light pink that is among the favorite of the eight shades. Grandma Mary Jo also inspired a bright red lip kit and the Kardashians' late father, Robert, inspired the shade "22" that is an orange hue.

Jenner's Instagram is the go to place to find out when the lip kits will go on sale next, the new colors and even new items for the Kylie Cosmetics brand.
