OK - the Quick Frost has arrived!!! On first inspection this is quite white in the jar. Its a creamy based pigment that is smooth to apply, not chalky. On swatch its incredibly sheer - in fact its sheerness is similar to fairylite, its very sheer, and just like fairylite it also has a nice shimmer. The colour is a very sheer white with a super pale green shimmer - almost a sheer iridesence with green shimmer.
I am about to get some swatches, will take me a bit and I will post them in the swatch thread
ETA - I have compared this to the White Gold side by side and they are not terribly similar, different texture, different colour (unless you apply this Quck Frost heavily, then it is a closer match, but still way less shimmer than White Gold), and this is way less shimmery than White Gold. Overall this ISNT a wow pigment, just a nice pigment that most people would probably use as a highlighter because the colour payoff isnt fabulous.
