Okay, Archibald, I have tried out a few of your packs.
I have tried out the Plymouth theme, Mud World Black, and it works as well as it can. Looks very dark, but it does
have the word "black" in the title.
I have tried the KDM theme fluorescent world (as well as the Ksplash equivalent), contrast, wet air, and dry air. Those seem to work and they look nice, too.
