Describe the bug

For a long time I have a launch configuration that I use, but ever since version v0.2026.01.28.08.14.stable_04 my launch config no longer works (unsure about the exact version - I mean there are so many - but it must be an issue with a very recent version). It's no longer listed when I open up the Launch Configuration Palette.

I haven't changed my launch config in a while, so I'm pretty sure this is a regression.

After fiddling around I have found the issue:

Previously I had this: color: Green. this no longer works it seems, I now have to use this: color: green (note the value for the 'color' property no longer starts with a capital).

Perhaps I'm not aware of some documentation update (or whatever), but I wanted to share my findings in any case.

To reproduce

this launch config fails (it doesn't even show up in the Launch Config Palette)

name: Default Launch
active_window_index: 0
windows:
  - active_tab_index: 0
    tabs:
      - title: Test
        layout:
          cwd: /Users/<USERNAME>/
        color: Green

when changing the color value to lowercase, the launch config shows up again.

name: Default Launch
active_window_index: 0
windows:
  - active_tab_index: 0
    tabs:
      - title: Test
        layout:
          cwd: /Users/<USERNAME>/
        color: green
