Strange Splotch On Skin Why Would My Finger Turn Purple?

Why would my finger turn purple? - strange splotch on skin

There are a couple of days I'm in purple nail polish on her fingers and feet. Everything went well except for my fingers on my left hand. Turned parts, with light purple dark purple stripes in it. I have nothing else to do. Today, my finger is purple. Seems to be the production of the nail. It's driving light violet. The town is growing all the time. Seems to be under the skin. I have a small cut under my fingernail. Do you think it might have something to do with it? What should I do?
It does not hurt or what though. Everything seems strange.
