Hi,
we had set more color in SG 1.1b4. To know how, check this thread:
A little extension for text color schemeThe scheme should be backward compatible and a reference page is available there:
Color codes - WolfWikiAbout the black color, we have noticed cheaters and TKs are often using this color to hide their name making it harder to be read by other players... Their goal is to be kicked as late as possible. So we just disabled this support in SG 1.1b.
So it's possible your black part is just taking the colour from the previous part. But tell us if you think there may be a bug. But in that case, show us your complete name string, so we can check.
