well there haven't been any pokemon palettes (or any nintendo palettes as far as I know), so Big Band getting one is quite a precedent.
What about Samus Parasoul and Ditto Double?
Its not Samus its Armstrong from FMA.
I heard its a reference to the McGee Alice in Wonderland games.
My bad. I've heard so many people in the past say the Armstrong was Samus I forgot about Justin Bailey.
Parasoul has a FMA palette and a metroid palette.
It could be Robocop.
On last night's Lab Zero stream, Brady said that BB's color palette No. 2 is based on Kolchak the Night Stalker. It was at the very end of the stream archive.
I believe the orange colors were confirmed by Mike to be original and not based on anything.
If it isn't said so in this thread the answer is likely "Officially no", but nothing's stopping you from perceiving it as such.
I make an effort that every character has a black/white/gold palette. Several of them end up not making final pass, though.
Please please tell me there is a reference to Sherlock Holmes's three pipe problem.
