What's a Girl to Do?

I have two rows and the bind off left to knit on Charlotte. I probably have 1 1/2 rows' worth of yarn left on the color that I'm currently working. Herein lies the dilemma. I can:

a) Switch back to either the light blue/green/purple or the purple/grey/black yarn to finish the last two rows and bind off;
b) Rip back a couple of rows and shade in some of either of the above colors;
c) Add a completely new, but complementary color (specifically, colorway 317, which is dark blues, dark greys, and maybe a hint of purple and a hint of black);
d) Bind off now and skip the last two rows.

Anyone have suggestions? I will sleep on it, since my hands are about done for the night.
