NARS Koliary is part of the Spring 2012 NARS collaboration with designer Thakoon Panichgul. This is the only polish I have from the Thakoon collab, and I found it on eBay. The polishes from this collection were unfortunately limited edition, but they do have a good reputation for being some of NARS’ best polishes!
Koliary is a vibrant “cyan blue”. The formula of this polish is perfect and I love how bright this shade is! Luckily, there are similar shades out there if you can’t find this. According to Temptalia, Zoya Robyn is a little lighter than Koliary, so that might be a good match (I do not have Robyn so I can’t compare!).
I love this color and can’t wait to wear it on my toes this summer!
