Code that does pretty much the same thing in Python language:

def color_dump():
    i = 0
    j = 0
    k = 0
    side = 0
    global buf, bufe    
    print ("\r\n\033[1;33m* * 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F ** 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F *")
    for i in range(0, 512):
        if ( not (i % 16)):
            if ( not (i & 16)):
                print ("\033[1;30m%02X " % (i / 32) ),
                side = 0        
            else:
                print ("\033[0;32m%02X" % (i  / 32) ),
                side = 1
        if (side == 0):
            print ("%02X" % buf[j]),
            j = j+1
        elif (side == 1):
            if (k % 2):
                print ("\033[1;36m%02X" % bufe[k]),
            else:
                print ("\033[1;37m%02X" % bufe[k]),
            k = k+1
            if ( not (k % 16)):
                print ("\r\n"),
    print "\033[0;37m"
buf = []
bufe = []
for x in range (0,1024):
    buf.append(0)
    bufe.append(x)
color_dump()
