I've been looking for brighter coloured eyeline pencils for ages and I just discovered a new brand - it's just called 'Make Up Store' and I think it's Swedish originally. Anyway, they have a great selection of coloured eyeliners - even larger than MAC's. I've also been really impressed by the staying power. Not cheap, though, sadly.
There's a 'make up store' here in Australia. They have a wide variety of things and their range of colours is very good. It's very arty makeup, not basic at all.
