+**Toggle based on background value?**
+
+```lua
+-- set background=light will change flavour to latte
+-- set background=dark -> mocha flavour
+vim.api.nvim_create_autocmd("OptionSet", {
+	pattern = "background",
+	callback = function()
+		vim.cmd("Catppuccin " .. (vim.v.option_new == "light" and "latte" or "mocha"))
+	end,
+})
+```
