Clover Emblems still use SKINCOLOR_EMERALD even though its original color was renamed to Shamrock
I don't have old footage to prove this, but the devs did it for me apparently.
This was probably taken while testing Sal's original merge request, instead of actually being of 2.2.12 like the site post presents it as. This is what the emblems look like now:
I know though that the extra hue-shifting is more pleasing to some though, especially considering the mystical nature of the emblems, but none of the other emblem colors are like this, and neither was the old color, now Shamrock. One could either fix the issue directly, or update the other emblems' colors to match the hue-shift. So there's an excuse for why I didn't just... fix it myself.
