You can now use Dark Themes in Revit Schedules and Panel Schedules with the latest update to 2024.2, and you can customize these settings in your Options for Dark or Light Themes. See images below:

Image 1 – right click on your schedule on top of the columns to be able to add color (Edit Shading)

Image 2 & 3 – Go into your Options from the File menu tab, select Color to be able to customize your Dark and Light Theme color options but notice the schedules stay the same color when swapping Theme color.
