Purple Finger

I have no idea what’s going on here, but it happens from time to time. I had been rolling on wallpaper primer in two rooms for a few hours . I’m suspecting I held a tool in a certain way for a long time , or somehow blocked circulation to a part of this finger . It doesn’t hurt , but it is a little swollen.
The color got darker and lighter during the rest of the day. I did some shopping on the way home, and the store was cold , and that seemed to exacerbate the issue – finger got cold and numb and really purple . Back at home in my nice warm home office , it’s still discolored , but not as much.
