I have been manually porting the default Kitty theme (dumped with the get-colors) as well as a lower-contrast custom version to Wezterm and now Ghostty.

I attempted last night to set the colors manually in iTerm2 on an old macbook in order to generate a scheme and contribute here, but I could not figure out the exact mappings to iTerm2 as it seems to have several more options than a basic theme layout used by other terminals.

The Kitty Default color dump converted to wezterm TOML format is in my dotfiles repo as well as below. The ghostty key-value version can be found there as well.

[metadata]
name = "Kitty Default"

[colors]
background = "#000000"
foreground = "#dddddd"

cursor_bg = "#cccccc"
cursor_fg = "#111111"
cursor_border = "#cccccc"

selection_bg = "#fffacd"
selection_fg = "#000000"

ansi = [
    "#000000",  # color0
    "#cc0403",  # color1
    "#19cb00",  # color2
    "#cecb00",  # color3
    "#0d73cc",  # color4
    "#cb1ed1",  # color5
    "#0dcdcd",  # color6
    "#dddddd",  # color7
]

brights = [
    "#767676",  # color8
    "#f2201f",  # color9
    "#23fd00",  # color10
    "#fffd00",  # color11
    "#1a8fff",  # color12
    "#fd28ff",  # color13
    "#14ffff",  # color14
    "#ffffff",  # color15
]

The Low Contrast version only changes the background and foreground to be less harshly contrasted:

background = "#333333"
foreground = "#ffffff"

Would love any assistance so that I can contribute it here, thanks!
