I was pleasantly surprised to see the Modernist palettes available in Sephora. I am VIB Rouge but after the very mixed reviews, I wanted to swatch them in person. I ended up getting Obscura and Color Field. Yes, they can kick up powder. (I used MAC, Chanel and Shu) I wouldn't swirl your brush around because the resulting powder will probably drive you nuts if this bothers you. But they go on beautifully and when they are used with a damp brush, really gorgeous. I just tried to tamp down my brush on the final swipes to pick up any errant powder and that was fine for me.
Wet or dry, I didn't experience any fallout. The metallic shades do seem creamier than the mattes.
The formula is definitely different from their old duos (and the even older multipalettes they offered when they first launched). But I quite like mine so far - the colours really are gorgeous with a great deal of depth.
