   Hmm, on my machine, using gimp, the reference image 
shows the pixel value as rgba(246, 225, 118, 255),
and your generated one has rgba(247, 227, 119, 255). 
I can easily imagine reasons why the two would vary by 
a code value (or two).

   How are you checking the reference/output Image's pixel values?
