I find it very difficult to see the border between splits. How can I edit the split border colour please?

You can overwrite WinSeparator highlight group:

require("catppuccin").setup {
    custom_highlights = function(colors)
        return {
            WinSeparator = { fg = colors.flamingo },
        }
    end
}
