Prat has a feature that detects your name in chat and colors it, which resets the chat color afterwards. This means if it was part of a detected OOC/emote/speech, only the part before it will be properly colored. Since we have a Prat compatibility module, it would be good to look into that interaction and restore the appropriate color afterwards if possible.

This issue should be resolved on its own thanks to the color code behaviour changes in 9.0, keeping the issue open until the patch drops.
