title: Eclipse Color themes does not change font color
body: <p>I am using Eclipse Mars 4.5.1 on a Macbook to work with a Fortran Project. I recently installed Color themes from the Eclipse marketplace. I can see the list of available color themes. If I select one and try to apply it, only the background and the line number change while the font color remains the default one. For example the image shows the editor with the Monokai theme (which on the preview looks very different), all other themes behave the same way. How can I make the color theme apply to the font too?</p>
