You can use a TRichEdit for that. You can use its SelStart and SelLength properties to select the word and then use its SelAttributes->Color property to change the word's font color (or use the Win32 API equivalents). Refer to the following article for some details about how to implement a "syntax highlighter" with TRichEdit:
