There is a room for improvements. For example, all the Midnight theme buttons in the forum are either white or very bright blue. You can point them well. Except for the one posting a new reply. It's dark on a dark green background and black borders. Even forum's page numbers have white borders and they are well distinguishable on the background.
Also, I want to notice that the white background of the text field in a dark environment hurts the eyes. A bit grey component will do well.
