Questions about mushrooms

[Shazam311]

I have had these mushrooms I got from my local store and at first they were mostly brown. More recently I've noticed them turning a blueish color and am wondering if that means they are getting too much light. Or if it's a normal change in color for mushrooms

This is what it looked like when I first got it

I'd be willing to bet that it was browned out when you bought it and now it's returning to its normal, healthy color.
