I checked the values and they are 100% true.

    A5->A6 1C->1B

    Incremented and decremented by one point, respectively (didn’t look at the other values tbh, I only cared about B00B, A55 and D1CC)

      The “biggest” change is A7→ AB for the middle’s blue channel (4 units). However, since JPEG uses YCbCr 4:2:2 (¼ as much resolution for the two color channels that encode hue and saturation in a linear way) by default and blue is only ⅙ of a contributor to lightness as green, it’s explicable without malicious intent by the OOP.

        Here I go learning about entirely new color encoding systems. I know RGB, I vaguely know about HSV and CMYK, I know HSV has some siblings too, but somehow never came across YCbCr and its siblings before.

        Thanks for showing me a quaint new corner of nerddom <3
