When syntax highlighting affects coding practices

In eclipse, using the php extension, both 'and' and 'or' get colored in a bold dark purple, but && and || don't. Normally, the symbols are interchangeable in my head, I've coded for long enough by now, but I find myself preferring 'and' and 'or', just because it makes my code look more readable to me due to the syntax highlighting. Unfortunately, there's a difference in meaning, the operator precedence goes like:

||, &&, ... =, ... and, or

which could be a problem for me if I'm not paying attention some time in the future, and expect the wrong behavior. (And is also kinda goofy, this is why we use parenthesis)
