Minor improvement to aggressive chat messages (colon -> parens)

- Colon splitting race and color is very weird.
- Not using simple space because it's not i18n-friendly (some languages, such as English indeed, prefer the color before the race, while others prefer it the other way around)

Alternative: Define a ``bool`` for each language to define the color adjective position preference.
