Here's a couple pics of my collection (so far). Both taken indoors in electric light, the first with a flash, the second with a 'daylight' simulating bulb but no flash. They're applied dry, just a fingertip dab and swirled into a wee patch. Just for fun, hope it's some help.
p.s. one colour is a different brand, I took the pic to show the kind friend who gave it to me the comparison.
I find idolize and Slick to be very similar, with Slick less multi-tonal and a deeper grey. Fete and Chestnut, too, are very close in colour but with different finishes with Fete seeming pearlier and Chestnut a more intense depth of tone with a same-tone shimmer. I'm very open to enabling so please suggest more colours, too
