Feature Request: Support for Colored Text in Chat Messages

Many users, especially learners, would greatly benefit from the ability to format text with custom colors directly in the chat window. Color coding is a powerful tool for:
• Highlighting grammar parts (subjects, verbs, particles) in language learning
• Emphasizing keywords or concepts in educational content
• Distinguishing different types of information visually for better comprehension

Adding support for safe, accessible colored text—while maintaining readability and preventing misuse—would enhance the learning experience and make explanations much clearer and more engaging.
