I did a version of this and it came out really well. I used three
Sally Hansen Xtreme Wear polishes (they were $2 - $2.99... Apparently the product numbers don't match to what's on the site now, but all the colors are still available)
Lime Lights (22) - A very translucent seafoam color. I laid this down over a base coat, halfway down the nail twice and then 1/4 from the tip twice.
Marine Scene (23) - A very translucent ocean seafoamy blue. I put this over the tip twice, and at the very very tip once.
Disco Ball (either 09 or 60!)- A multicolored glitter in jelly (reflects blues, greens, yellows and pinks). I painted this in a line across where the Lime Lights fade into the clear nail, and then over the entire tip of the nail.
It looks great! I have two of these SH Extreme polishes that would work for this --- a red jelly and a pink jelly. They both have glitter so I may not need the glitter step.
I will try to get a pic of this! (edit: pics below. Excuse my cuticles and the skin surrounding my nails, this was just a test run for the polish)
