Only highlight enclosed color codes to distinguish from CSS-ID-Selectors

I had the problem that jQuery-selectors like `$('#addButton')` would be highlighted like colors. While I know that `$('#add')` will still be highlighted at least the confusion is minimized.
Might be an idea to add `\b` to other regex-selectors as well.
(Also, I didn't get why the pound sign `#` was inside the brackets, might remove them from `[r][g][b]` as well.
