Well, at the least, need a new muffler, bar, chain, buff down, sharpen, and repaint the bucking spikes, then you could go for sort of a middling color for the plastic. Maybe a metallic sparkle purple like I saw someone do to their saw at a GTG.
Or just go nuts, sandblast the colored surfaces, prime it, then do a neon orange/safety orange. Not the usually orange, but a painfully LOUD orange like this.

Or best of all, do the ultimately STUPID redneck thing. Paint the chainsaw with a camo color scheme.
Oh yeah, those will NEVER get lost in the woods
