Without further ado, here are the swatches:
L-R: Cocoa 831, Majestic 836, Earth 829, Amethyst 825, Rose Petal 840
Cocoa 831 is a neutral brown. This is what I'm talking about when I said Sleek brings more colour options to the table. I can't imagine Revlon or L'Oreal making a colour like this, LOL!
Majestic is a deep purple. Sleek probably didn't make this with the fairer ladies in mind, but I kinda think this one would be pretty cool even on fairer ladies, if applied sheerly.
Earth 829 is another brown - that's three browns out of 10 colours that Sleek has. Pretty cool, huh? The browns aren't all the same though - Earth has a bit more pink is and is a bit lighter than Cocoa, while Blaze (swatched in the previous post), is a cooler-toned brown than either Cocoa or Earth, and has a hint of grey thrown in. Blaze is also darker than Earth, and slightly darker than Cocoa too.
Ameythst 825 is one of those colours I also think would be super cool on. Pinky-purple (with an emphasis on the purple here) with a blue flash. Cool.
Rose Petal is a warm medium rose with gold shimmer. This is probably the most conventional colour of the lot, and a very lovely colour too.
As I've said before, the finish on these is smooth and quite creamy, and pigmentation is pretty good - as you can see none of these are annoyingly sheer, and all can be layered to opacity, or sheered out for a more subtle look.
