Hi there - I have parfait amour, and have had a lot of difficulty with it. It really needs the $239 brush - and to 'pat' / pack it on, without swishing. Any blending with the #217, will wipe it right back off again! I also have satin taupe, and whilst it's not as bad, it still prefers packing on.
The other thing I used to do it layer my lightest shadows on first (ie vanilla, then satin taupe, then carbon/smut), however covering the whole lid with vanilla, then makes satin taupe not go on as well, so now I just put vanilla on inner third, satin taupe on middle....etc and blend together rather than try to blend on top of...
I have found that mixing medium (make your own with 1 part glycerine to 2-3 parts water/ or rosewater) works, and there is a product called DuWop Payoff, which turns all pigments or pan shadows to cream - just add a drop directly onto the palette (or brush) - it works wonders! Makes everything double intensity, and also helps prevent fallout....
Bases (I use NYX crayon over a primer) helps heaps too...
