I tried installing a theme util from market place (Eclipse Color Theme 1.0.0) but I keep getting a confirm dialog and when I click it nothing happens. It says no repository found in git. When I try to change it in preferences. It doesn't change I have dark on dark text currently and can't read it very well.

The screenshot shows the preferences for the syntax coloring themes of Eclipse TM4E, which is used for instance by Eclipse Wild Web Developer for JavaScript, XML, etc. mostly in combination with a language server for code completion. Those syntax coloring themes are shown in the Generic Text Editor in the right-click Switch to theme submenu.

The UI theme you are probably looking for can be selected in the preferences General > Appearance instead.
