Eclipse background color unexpected behaviour

Question

I am trying to change background color for Eclipse. I want the editor background to be completely black. To make the UI respond I first have to choose a random color, as I do at step A in the picture. Then I can choose black, click Apply and I get the desired color as seen at step B. But as soon as I exit the settings dialog, the color changes back to step C. It looks like eclipse thinks the grey-ish color is actually black, I don't know. Does anyone know how to deal with this?

Not the best answer but I found a way to fix it. Im using moonrise theme.

Opened eclipse/plugins/ and found com.github.eclipseuitheme.themes.moonrise-ui, opened the jar file and edited the moonrise-ui-standalone_WIN.css file (yes im using windows 10, 64 bit (if that has anything to do with it(there were several similiarly named files)))

changed this block:

.MPartStack.active #org-eclipse-e4-ui-compatibility-editor Canvas > * > * {
 background-color: #000000;
 }

Now it seems to work just fine with black background.
