A Tails sprite for Sonic 2 has surfaced, and it looks like it is based on the SatAM TV show.

Discovered and published by @Fieryfurnaceas part of the DiC/SEGA America design documents dump.

Here's the post covering it all on SSMB:

What do you all think? Whoever found this found something rather interesting, if you ask me.

Fascinating.

Younger me never really thought much of Tails being brown in the show but as I got older, it did knag at me as he was clearly more of an orange colour and no Sonic character has ever been brown. It did make me wonder why. (Pause for inevitable Sally Acorn mention.)

It's rather nice to know that they might have been a legitimate reason for this brown colour at the time and wasn't intended as an oversight. Looking closer, he does still appear to be orange but it is a much darker tone. It makes sense that it could be confused for brown.
