title: What do the colours of functions in MySQL Workbench signify?
body: <p>In MySQL Workbench, there are a lot of built-in functions for performing different tasks. Some functions are just synonyms. But I notice that synonymous functions sometimes have different color representations. Like, curdate() is grey and current_date() is blue. The <a href="https://dev.mysql.com/doc/refman/8.0/en/date-and-time-functions.html#function_curdate" rel="nofollow noreferrer">documentation</a> says that they are synonyms. So is there any specific reason behind the color codes here?</p>
