I'm not sure I know how to even edit 's article on the matter until I've discussed it first. It seems that Slash's color keeps changing during the series, sometimes in the same episode. I'm not just talking about how he went from an olive-colored non-mutant to a blue mutant. But how he keeps oscillating between the extremes of blue and green. And in one scene, he's even purple.

For your consideration, in order of appearance:

Of course, I have a theory: Slash's color may be something like liquid crystal, changing color as his moods change:  blue for positive, green for negative, or something like that. When Slash first mutated, maybe he was blue because he was very happy to be entering a new phase of his life with Raph. But, indeed, he was still unstable, and he may have turned green during their time on the surface as his deeply negative emotions intensified. In Metalhead Rewired, he was blue when he was saving Raph's life. But in Newtralized!, Slash was feeling a certain hostility to Raph, and he was green...but then started to turn bluish when he and Raph finally made up. But I can't explain the green at the end of Battle for New York, Part 2.

As for Slash's eyes changing from amber (non-mutant) to cyan (new mutant) to yellowish-green (permanent), my theory is that he was most mutagen-saturated just after his mutation, and that glowing cyan in his eyes was actually the color of mutagen dense in his blood, which faded rather quickly within the same episode.

And Slash's yellow lower jaw...I can't easily explain this either. But it does have the effect of making him look more...worn. Like he has a five o'clock shadow. Or maybe he's slowly yellowing to death, or his mutation is gradually regressing, or something. XD I dunno.
