Believe it or not, I have never tried a GPS or a Pearlglide e/l. From the descriptions of these colors though, that will definately change! I am put off by the "grease" part of the paintstick. Is that because they have black bases? Or do they give the wet eyeshadow look? Either way, I am likely to pass because I am afraid of black, other than eyeliner and mascara. On my list though, are four of the pearlglides:
Almost Noir - Dirty plum (Limited Edition)
Designer Purple - Iridescent violet (Limited Edition)
Petrol Blue - Deep navy (Limited Edition)
Undercurrent - Blue teal (Limited Edition)
