to reset to default

MySQL Workbench 8.0.13 doesn't support the new dark mode of macOS Mojave yet. This will come with a future release. Until then keep using the light mode if the use of MySQL Workbench (and other software which still needs to be updated) is essential for you.

Update

Starting with MySQL Workbench 8.0.14 the new dark mode is fully supported.

defaults write com.oracle.workbench.MySQLWorkbench NSRequiresAquaSystemAppearance -bool yes

Run this in CMD
