The Kardashian sisters are adding Christmas colours to their nail varnish line.

Kim, Kourtney, and Khloe have revamped their Nicole by OPI Kardashian Kolor nail polish collection by branching out with a new festive themed range.

Suzi Weiss-Fishman, OPI's Vice president and artistic director, said: ''Try the vibrant red, purple and teal for a jewel-coloured look, or one of the glittering shades for classic holiday sparkle - both important trends for the season.''

The six new varnishes have been given some appropriately festive names: Keeping up with Santa, Deck the Dolls, Here we Kome A-Karoling, Kardashing Through the Snow, A Gold Winter's Night and All is Glam, All is Bright.

The new products will be available in November at US store Target, priced at $8 each.

The sisters are also expanding their retail empire by launching a new make-up line called Khroma Beauty around Christmas time, which they have dubbed as ''affordable'' yet glamorous.

Kim said: ''We've always wanted to release our own cosmetics line, so this is a dream come true. Our Lash Dash luxury lash collection will debut this holiday season, with more products coming in the new year.''
