Cult Nails My Kind of Cool Aid is a very cool-toned, very dark lavender with a pearl finish. It is a permanent nail lacquer that retails for $12.00 and contains 0.5 oz.
Cult Nails My Kind of Cool Aid Nail Lacquer ($10.00 for 0.50 fl. oz.) is described as a "purple/gray" or "gravender" as Cult Nails calls it. It's a light-medium grayish purple with sparse white shimmer that's opaque in two coats. I'd say the closest shade I have to it is Rescue Beauty Lounge Insouciant, which is a few shades darker and less gray. Shades like Nubar Purple Aster and Zoya Marley are much lighter.
