I was previously using a different product to create my .dmg file and attach a license to it, but there is an issue with Dark Mode in Mojave. The Software License Agreement text appears black on the dark background and is hard to read. I just installed the trial version of DropDMG and it's much better than what I was using, but I tried adding a test license file and I ran into the same issue.

Here's a screenshot:

Are there any configuration settings I can use to fix this? It seems that the formatting applies mostly to editing the font/colors/background image statically. Ideally, the text would show up black in Light mode and light grey/white in Dark Mode.

Thank you!!!
