catppuccin_latte.vim sets background=dark, causing reload loop and fallback to default colorscheme

[feinburger244]

Summary

colors/catppuccin_latte.vim contains set background=dark on line 2. Since Latte is the light-mode variant, this is almost certainly a copy-paste from one of the dark variant files. The wrong value causes two problems: downstream consumers of &background pick dark-mode defaults against a light palette, and any user who tries to correct it from their vimrc triggers a colorscheme reload loop that ends in Vim falling back to default.

Reproduction

1. Install the plugin via Vim 8 native packages:

   git clone https://github.com/catppuccin/vim ~/.vim/pack/themes/start/catppuccin
   

2. In ~/.vimrc:

   if has('termguicolors') | set termguicolors | endif
   syntax enable
   set background=light
   colorscheme catppuccin_latte

3. Open Vim and run :verbose set background?.

Expected

background=light, last set from the user's vimrc or from the Latte colors file.

Actual

background=dark, last set from catppuccin_latte.vim line 2 (or, if the user puts set background=light after colorscheme, the colorscheme reloads in a loop per :help 'background' and Vim falls back to default, observable via :colorscheme returning default despite catppuccin_latte.vim appearing in :scriptnames).

Environment

• Vim 9.1, macOS (also reproduced on Vim 8.2, Linux)
• No other plugins installed
• +termguicolors confirmed

Fix

Change line 2 of colors/catppuccin_latte.vim from:

set background=dark

to:

set background=light

The other three variants (frappe, macchiato, mocha) correctly set background=dark and should stay as they are. Happy to send a PR if that's easier.

Why this matters

set background in Vim is a functional declaration of the actual terminal background, not a metadata label. Syntax files, plugins, and Vim's own highlight defaults branch on &background to pick readable colors. A light colorscheme declaring background=dark means every fallback path picks dark-mode colors that render poorly against Latte's light background — and, as shown above, users who try to correct it externally hit a reload loop because of the behavior documented in :help 'background'.
