I don't know how long they're around for, but I do know that, when available, they're only in store in Boots stores. So keep an eye out if you want to add them to your collection.
When it came to getting in to town to try and get these (which I wasn't sure I'd manage as I only go to town every 2-3 months) I knew I had just over £10 worth of points on my Boots Clubcard so was expecting to just pick up two of these (as they're £4.99 each), but when the time came they happened to be on a 3 for 2 so I got all three of them for £9.98 worth of points - Bargain.
The shades are 'Creme de Rose', 'Creme de Nude' and 'Creamy Beige' - If I'd only been able to get two I probably would've got the far left and far right shades as the Nude shade is a little more yellow toned than I'd normally opt for; that said, I expect it'll make a great base shade for a number of looks as Color Tattoos are one of the only things that never crease on my eyes.
As their name suggests, they are matte shadows which lends them to being fantastic on their own or as a base with a more shimmery powder shadow over the top or in the crease. I really, really am hoping that Maybelline bring us some more shimmery neutral Color Tattoos, too, as we're seriously lacking in them.
And, for the swatches. They're in the same order as above, and you can see they're really quite lovely shades. My favourite is, without a doubt, 'Creme de Rose' (Which I keep reading is said to be a dupe for Mac's paint pot in 'Painterly', but I don't have that so I couldn't comment). If they're still available next time I'm in town, though, I do think I'll try and grab a second one of this shade, because it's just such a perfect shade for adding the tiniest of colour to the lid, or just to even out the skin tone if you have pale skin like me.
All three of them are lovely and creamy, though, they aren't drying and, thus far, haven't creased on my lids. I haven't used Nude, much, though as it's just a bit yellowy for me, but I'm sure I'll find a good way to use it as it's a Color Tattoo and I can't help but love them.
So, please, please, please Maybelline. Make this range permanent, and bring us some more neutrals, alllll of the neutrals!
