It's more obvious with the image (which should be loading now) but I'm talking about custom icons. Like having a fire icon be red/yellow while the rest of the text has its own color.
The richtextlabel does font+sizing etc differently*, I don't like seeing pixels (can be dialed in, but not my favorite to require) though at least for the standard label the new stacked effects are a bit snazzy (and theme-like) so I guess I don't hate it now that I do have it dialed in.
* which does not surprise me given the other text methods all have benefits and drawbacks (and even with the 2D label, color emoji can kinda look off with outlines but that might be down to the font?)
