ELI5, Why are the ends of our nails always white?

Even when I cut the ends off the ends turn white within a day?

Nails are naturally white-transparent, but most of the nail is joined to the finger underneath it, so you are seeing the color of the finger through the nail. The end of the nail is detached from the finger, so you are seeing the color of the nail there.
