I think a different name would be fine. The constants are actually only
used once each. Their main function is to avoid a confusing parameter
'3' to the color_output function. But we could use the literal
constants with a parameter, like:
diff --git a/color.c b/color.c
index e2a0a99..809b359 100644

}
We could also pass in integer "30" and "40", and then format it with %d
inside color_output. I don't know if that would be more obvious or not.
