Highlight modes are dependent on the file types you are editing. They are useful because they highlight different types of text into different colours. For example it is useful to put all comments into a specific colour. Important language specific keywords can be highlighted in a different colour. Usability wise your brain will then be able to ignore unimportant text and concentrate on important text, simply by colour.
