According to Pumpkinangel on Livejournal:
Shadowy Lady quad - beautiful! Smudged Violet is more neutral and less brown version of Satin Taupe, Lightfall is nothing unique but goes well w/ the quad, similar to Next to Nothing e/s from Smoking quad
Spiced Chocolate quad - very warm but wearable, Sweet Chestnut is not chestnut at all, it is like Artifact p/p, redder and deeper than Cranberry but still a berry shade not a red, Brash is a more orangey Amber Lights and Honey Lust, more coppery compared to Firespot, less brown (or gold) compared to Mythology, Spiced Chocolate is cooler compared to the SW and Brash, it is still a brown on the warm side, warmer version of Showstopper (which can get too grey-ish at times)
