AWK and friends.

Look mom! I've shaken the colors away!

The 'x' file:

BEGIN {
    N=5
    C=2^N
    print "P3\n"2^(3*N-int(3*N/2))" "2^int(3*N/2)"\n"C-1
    for(x=0;x<C;x++)
        for(y=0;y<C;y++)
            for(z=0;z<C;z++)
                print x^4+y^4+z^4"\t"x" "y" "z | "sort -n | cut -f2-" 
}

Run:

awk -f x > x.ppm

Output:

N=5:
