Just a quick note:
I posted a review on the Urban Decay Black palette here earlier in the year. The palette features exactly what it sounds like, a series of blackened jewel tones. Now MAC has released Fall Colour Pigments in Emerald Dusk, Starless Night, and Blue Storm. I wasn't too dazzled by the pigments, but you can see swatches here. Feel free to comapre and contrast between the two sets. I personally think that if you already have the Urban Decay palette, you don't need to buy the new MAC pigments. They're not exact dupes, but they could be easily interchangeable.
