Perhaps in theory. Almost every application under the sun I've encountered expects 1 to be red, or 4 to be blue, or 3 to be yellow, or whatever. As an example, take solarized, or really any of the base16 themes. When I've used solarized in the past, many terminal programs that expect to print something in red are actually printing in a slightly-dimmed-background color, or purple, or something else where the intention of the tool author and the intention of the theme author conflict.
