A strange color acorn

I knew there were acorns on the ground under our big tree so that was going to be my tiny Tuesday blip.   But this one really caught my eye,  no editing here, just a crop closer because I was too lazy to go back inside to change the camera lens.    It looks almost bluish purple where all the others around it are brown or green depending on how long they have been on the ground.

Maybe this one is a female and she got tired of that same old dull color!
