Looking for a bright violet

I am looking for a bright purple--violet, really--that is not greyish or dull.  I am considering the TAG purple and their neon purple, but would love to see the difference.  Can anyone do a picture comparison?  Or have any other advice?

I may be a little late on this, but I figured it wouldn't hurt.  The one on the bottom is Tag regular purple, the one on top is the Neon purple.  The regular purple has a little more pink to it, and the neon is not as opaque but is a really nice violet color.  With all the tag neons I've noticed you have to load more and sometimes apply a second time for a really nice color that doesn't seem splotchy (this swatch was still a little wet when I took the picture.)

Thank you so much, thou ... I love the regular one on the bottom! Just what I'm looking for ...

Fab Purple Rain is an amazing purple. It almost has a day glow affect

Thanks, bunchwife!
