www.theeverydaybeauty.com suggested I might have a look at Bobbi Brown Lavender Metallic eyeshadow as a possible Bright Winter icy violet. I've been looking for a lilac version of Dior Monoshow Bikini (a sparkly but not frosty clear, cool pink) and BB Lavender is really quite good for this.
Picture below is buffed onto my lid and up to my crease, and underneath my lower lashes. This isn't as sheer an application as it looks, although I did buff it in well. The lavender blends with my natural skin colouring, giving a bit of a glow without shouting PURPLE EYES. I do think it needs the definition of the Black Ink with it though. Dior Bikini is a softer and possibly more flattering look (the Lavender is more stark), but I like the Lavender for a change.
I find the Black Ink gel eyeliner much easier to control than MAC's Blacktrack, which is just a bit too intense for me. BB's is a softer black, although it still gives a good definite line.
