Tread Gently is a yellowish green sparkle which sounds horrid but it is actually pretty and can be used over lipsticks to add sparkle as well as moisture.
Purring is a tangerine shade which gives the lips a subtle hint of colour. It would be nice to add some shine and maybe some more warmth to a coral lipstick too.
Hot 'n' Saucy is a red tint on the lips. It is the most pigmented shade and my other favourite from the collection.
These pictures aren't the best to show them, I always find capturing sparkle really hard. Just go see them for yourself, they are lovely. I want them to bring out a hot pink and a sparkly pink oh and maybe a violet haha!
