Have a look here, there's a good selection of pink loose shadows for $1 a sample, and nearly all of the Pure Luxe shadows I've tried have been really good.

The only pink one I've got is Supernova, which is more of a peachy pink than I think you're looking for, but it's GORGEOUS. Great colour payoff and loads of sparkle. And for a dollar, the samples are HUGE.
Oh, and I also have Ouch! Personally I see it as more red than pink, but it's definitely a strongly pink-toned red if you see what I mean. Candyapple coloured is a good description. It's MARVELLOUS, really nice.
They also do blacklight active hot pinks in the "Speciality eyeshadow" section I notice, but personally I'm a bit wary of blacklight/ UV-active shadows as I heard (probably not true but I dunno) that they can be bad for your eyes......
Hope this helps and let me know if you purchase any of these pinks, and if you like them! (SO tempted by Brat, Bloom, Bubblegum or Smug!)
