After messing with #darkmode the last couple of days I’m reminded of how way back in #Windows95 you could set a theme for the system UI by choosing individual colors for window backgrounds, borders, buttons, dialog boxes, etc. I liked to set the standard gray background to sepia and see which programs used the system colors and which hard-coded gray, making their UI a weird patchwork where their custom components weren’t the same scheme as the built-in ones.
