Two-tone eyes

Deciding to have two-tone eyes is a bit like deciding to commit bigamy: you love one, but can't be without the other, so you drop your keys in the bowl and see what happens ... Hang on, that's something else. Anyway, there is something about this look that screams 'greedy'. You can't decide between blue and green, so you think you'll have both. That's all well and good, but make sure you give both enough attention - two-tone eyes need to look deliberate. You want colours that complement, not clash, but that doesn't mean they should be in the same family (we all know what that's called).

Green and blue is probably the easiest combo to start with, but since beauty companies usually do the matchmaking for you, why not be a bit bolder? Once you start mixing shades, be sure to prepare your canvas properly with a good base, otherwise all you'll end up with is a smudgy mess.
