That's interesting, but I don't find it alarming at all. It's uncommon, but not at all unheard of for ball pythons to shed out different colors over a period of time and then usually return to their normal coloration in time. It's also happens sometimes that after a shed, you'll see patches of grayish (or uncolored) scales...this is also normal and will usually go away with the next shed. I can't tell from your pics if this is a case of color change...or an unusually widespread case of "dry scales" (how I think of the patches of miscolored scales)....but in either case, it's not harmful to the snake and there's not much you can do about it but wait and see what happens.
There's a lot we don't know about their physiology and these color changes fall well within that mysterious zone. (At least, so far as I know! LOL)
