Now, this is the Cryptography department, not the art department.
I dug up an old CFRG mailing list thread about Curve25519 and the alternate formulas that were discussed in the paper.

One was named PinkBikeShed, the other was named FuschiaBikeShed.
So I quickly sketched both of these down as options to vote for:
y^2 = x^3 + 464586x^2 + x mod 2^255-19
y^2 = x^3 + 358990x^2 + x mod 2^255-19
I then wrote my username next to the formula for FuschiaBikeShed. :3
