Research direction
Investigate the markdown preview plugin's LaTeX rendering code, likely using MathJax. Look at how macros like \newcommand are handled in the MathJax configuration (e.g., in the preview server's JavaScript files). Check if the red color indicates a parsing error or a missing macro definition. Compare with how other LaTeX commands are processed. Consider examining issues or PRs related to LaTeX rendering in the repository for context.
