Rainbow nails are the shit, whether you're matching a full-on rainbow wedding or just want to sneak in a little funky touch. Twitter user @exceedingly sent us this video tutorial on how to create that water-marbled nails look. And of course, you can do this with any color combination!

Full disclosure: this looks pretty advanced. Try it a few times well before the wedding to make sure you've got the technique down. Or just take the photos to your manicurists and see if they can tackle it for you. If all else fails, rainbow glitter nail polish or nail bling to the rescue.

Anyone doing fancy pants nails for the wedding? Let us know in the comments.
