This icon was made back when remedy capsules were just blue versions of the tier 1 health capsule. Since the icon change, remedy capsules take on the tier 2 health capsule in appearance while still being blue. While it might just be left behind legacy of sorts, the visuals don't match up with the pills in game anymore. Swapping the icons might be worthwhile.

I mean this isn't some huge deal or anything, just something I noticed.
