The colour is a very pretty, well, grey blue (surprise surprise!) and as well as by itself, I also tend use it to add a flash of colour over an already applied black baseline, especially when I'm wearing false lashes as I am here (Eylure Hed Kandi Twisted Disco) to conceal any join lines :)
The consistency is really good, generally needing only 2 coats to get a firm block colour, and the brush is fine whilst managing a good sized line first time around and is easy to wield. As for durability, it pretty much lasts all day, with only a quick re-application of the outer flick required. I also like how it doesn't bleed into the corner of my eye if I attempt to line my upper lid all the way (my E.L.F liquid liner literally fills my tear duct with colour and scares the hell out of me for about 5 minutes until I've baby wiped it all out and ruined my make up!).
Overall, fine holiday fun and when my 9200 black liners have run out I totally plan to get this in black (I need to learn to kerb my addiction first) ;)
