Wrong colors in ghostty

[bomgar]

Describe the bug
Wrong colors in ghostty.

I set the background color to #ff0000 and took a screenshot in ghostty and wezterm. Wezterm uses the correct color.

This fixes the problem:

TERM=xterm-256color k9s

The default in ghostty is this: xterm-ghostty
I assume terminfo is not used correctly.

Expected behavior
red is red

Screenshots
wezterm

ghostty

Versions (please complete the following information):

• K9s: 0.32.7
• ghostty: 1.0.1-dev+0000000

This seems to be an issue with ghostty, as it affects the rendering in multiple different apps and works in other terminal emulators. I'd wait to see what the ghostty devs have to say about it.

Re-posting my comment from the Ghostty discussion on this issue:

k9s uses tcell, so this is likely an issue upstream with that and I'd guess would be addressed by: gdamore/tcell#763

This release has the ghostty support.

k9s has been running off a fork for 2 years now. This might get tricky to update without knowing what has originally caused the issue in the lib.

Possibly the broken thing was #1943, but there is no reference to any upstream issue that could be tracked.

I think it's related on reading the TERM environment variable. Ghostty has it set to xterm-ghostty, which is not recognized by some libraries I suppose
