Having owned a few my guess is that it hazed up outside the holder. This is common in 36-42 proofs, in fact its rarer to find one that isn't like this.
I can't for the life of me image this one very well through the NGC plastic, its graded Proof 67 and it much lighter as the reverse colors are more akin to poweder blue, pink and lemon yellow.
I would get some "MS70" solution and try to remove that haze. It's really impossible to even give a grade guess because of the haze and proof coins in general are hard to grade from pics.

Hell, I don't need to exercise.....I get enough just pushing my luck.
Most people don't like that type of toning and will not buy coins like that - hence the propensity to give it a bath.
Hard to tell about the technical grade - if sent in 'as-is' I would guess pf64 - but that is just a guess.
