So when I asked my boyfriend what colour eyeshadow I should put on yesterday, I wasn't totally surprised when he pulled a mischevious face and said "Yellow!".
I'm not a piker though - it took about 10 minutes but I finally dug out my one yellow eyeshadow and got to work with it.

Here's what I used:
Urban Decay Eyeshadow Primer Potion
Ruby and Millie Eye Colour Yellow 220M
Illamasqua Yearn eyeshadow
MAC Fluidline (Blacktrack)
Maybelline Full'n'Soft mascara

I'm actually really pleased with this. (Apart from the wonky-looking eyeliner in the second picture - it was alright IRL.) The yellow brings out the green colour in my eyes, which I hoped it would. The green accent on the crease helps too.
