Don't PNG images only have 3 color channels?

e.g., #EDEDE9E9E1E1

identify -ping -format \"%w %h %k %b\" $tmp_fp_file

No they can have 4 if you count the alpha channel. But you have 12 hex values. So that means you have a 3 channel 16 bit image. Your imagemagick is likely Q16 (default) which means 16-bit compile. So you can get that kind of value for colors. See https://imagemagick.org/script/color.php
