Scala projects look awful with Eclipse Dark Theme [closed]

Question

I love Eclipse Dark Theme for Java projects. However, Scala projects are almost unreadable:

What can I do to fix this? Are there specialized Dark Themes for Scala projects?

Answer 1

Okay, until someone does a better job at this, besides my above comments, I figured another theme and a way to get it, you can install any existing java theme, then modify the scala ide colors as you wish. https://github.com/guari/eclipse-ui-theme https://marketplace.eclipse.org/content/eclipse-moonrise-ui-theme

Export your preferences and add these at the end and then import:

Then, edit the colors to your liking here:

It ends up looking like the Java equivalent.

Of course, don't forget to share!

Answer 2

Because Scala has additional color settings, you need to use a theme designed for it, or be willing to tweak a lot of colors.
