When you make a loose fist and your knuckles appear white, it's typically due to a temporary reduction in blood flow to the area. The pressure from the muscles and tendons contracting can compress blood vessels, leading to a paler appearance in the skin over the knuckles. Additionally, this can be exacerbated by the natural elasticity of the skin and the underlying tissue. Once you relax your fist, circulation returns, and the color should normalize.
