Fix: unusable monster color in devteam member tile

Tile compilation was complaining about colors being used that had no
gray mapping (despite the color in question being gray...) since there
are only gray mappings for the first 16 colors.

Fix this by just changing the colors to those of the hand and cloak
respectively.
