Creating an RGB Value using sprintf() would be sprintf(’#%02X%02X%02X’, $red, $green, $blue);

Should also be noted that number_format() returns a string, so perform all numerical calculations before using number_format().

Also, another alternative to sprintf() for zerofilling is the str_pad() function:

echo str_pad(6, 3, “0″, STR_PAD_LEFT);
