text_fg_override_threshold B&W issue with themes kitten

[KenMacD]

Describe the bug
When text_fg_override_threshold is set and kitty +kitten themes <theme> is used, it will change the terminal to black&white. If used with --reload-in=all they all become black&white. Open a new instance does show the new theme though.

To Reproduce
Steps to reproduce the behavior:

1. Add text_fg_override_threshold 5 to kitty.conf
2. Run kitty +kitten themes 1984 Light or kitty +kitten themes 1984 Dark
3. See the loss of color
4. Open a new kitty instance and it shows the new theme correctly
