When it’s cold outside, the tone of your skin changes as it gets to your fingers. Your digits shift from their normal hue to white or blue, and they might turn red after that. But this might not occur because of the fact that temperatures have dropped. Instead, there could be a more serious explanation for the changing color of your skin.

It doesn’t take much to trigger such skin changes in a person who has this condition. Walking outside and into a frigid car on a wintry morning can start the symptoms. Or maybe it could be a breeze of cold air blown by an indoor air-conditioning unit. Indeed, even reaching into a chilled refrigerator could make a person’s fingers change colors.
