Clionadh Permafrost is a slightly warm-toned, medium purple with a frost finish. It is a permanent eyeshadow that retails for $5.25 and contains 0.06 oz.
Clionadh Permafrost Duochrome Eyeshadow ($4.75 for 0.06 oz.) has a blackened base with more, medium purple shimmer that had more of a frosted finish. The texture was a bit stiffer and thinner to work with, and there seemed to be a little bit more slip, which resulted in the product not adhering as evenly as other shades I've tried in the range.
It worked better with a fingertip or a dampened brush. The color coverage was mostly opaque in a single layer and lasted for eight hours on me.
