Due to what looks like a copy-paste error, previously it didn't pad the
blue hex value. This meant blue values of 1-15 would display as
e.g. "f0" instead of "0f" and looked nothing like the actual color.
Previously a dark grey of 15,15,15 would get a preview splotch of bright
blue; this fix makes the splotch display as the same dark grey used
ingame.
