The color handling of iproute2 was inherited from other utilities such as vim.
There doesn't appear to be any library or standardization, all this ad-hoc.

In current vim:

    char_u *
term_bg_default(void)
{
#if defined(MSWIN)
    // DOS console is nearly always black
    return (char_u *)"dark";
#else
    char_u	*p;

    if (STRCMP(T_NAME, "linux") == 0
	    || STRCMP(T_NAME, "screen.linux") == 0
	    || STRNCMP(T_NAME, "cygwin", 6) == 0
	    || STRNCMP(T_NAME, "putty", 5) == 0
	    || ((p = mch_getenv((char_u *)"COLORFGBG")) != NULL
		&& (p = vim_strrchr(p, ';')) != NULL
		&& ((p[1] >= '0' && p[1] <= '6') || p[1] == '8')
		&& p[2] == NUL))
	return (char_u *)"dark";
    return (char_u *)"light";
#endif
}
