Night Goblin color scheme

Dear readers, I need your help. My next project will be a Night Goblin unit but I cannot for the life of me decide on the painting scheme. In particular, I'm having trouble deciding on how to paint their robes.

I'd like to tie them together with the rest of my larger orc force (my old Night Goblin units will be updated with the new color scheme as well), but I still like to make them slightly unique looking. I've managed to narrow it down to two options, and I'm asking you to lend your opinion and help me figure out how they should look. As always, click on the pictures to see more.
