Ironically enough, that's a platform choice: it's the tractor emoji glyph, U+1F69C. On lots of platforms it's red or yellow :-) (Not on desktop Firefox, which is where my screenshot came from in the blog post.) Switching to dark mode may help it be a little more visible for people who find it a problem? It's a good point, though...

Oh no, I wasn't talking about visibility. Just that a certain tractor company has a trademark on the green and yellow color scheme. And they win in court.

ha! OK, I didn't know that. Well... whoever draws emoji on such platforms ought to know about that. Maybe I'll file a bug...!
