Paalanen: Developing Wayland Color Management and High Dynamic Range

There are a lot of text-based applications that have very fervent user bases. And these days, it's *mostly* possible to detect whether a terminal supports 8 colors, 256 colors, or true color (24-bit, 16 million colors) using various terminfo capabilities. The thing about 8 colors is that you normally use a fixed palette which can be customized in the terminal emulator's settings, and different emulators have different defaults. The same 8-color application may look different on different systems, and the user may further customize those 8 colors as they see fit (e.g. using per-application terminal profiles). On the other hand, it's not really possible to customize the higher-depth color spaces without explicit application support. So I have to wonder if there have been any similar incidents when an app started autodetecting color depth and switched from 8 colors to 256 colors or true color, suddenly "breaking" lots of setups at once.
