Staff members on the wiki receive special name colorations to help their user names "stick out" on the wiki and attract users who need assistance. Personally, I feel that white color for chat mods offers little contrast, given that other text in the Recent Changes and elsewhere is also white. Others on the chat have expressed solidarity with the issue. I recommend changing the coloration to a bright pink or purple for contract. Either #8A2BE2 or #FF007F would suffice.
