Ok. Yeah. Nevermind on those theories. First sum is 57, other is 50. The number set formed by the first six digits is not prime on the first one, but prime on the second one. Also, of course its a hex color. It has six numbers. Silly me.

but wan't the second image a QR code and not a url?

The eleven digits in the url from the solution page you go to. See if that sums up to digit 7 or 77.
