The video shows a close-up of a person's hand with nails painted in a gradient of colors. The person is using a piece of tape to separate the colors on their nails. They carefully apply the tape to the edge of their nail and then paint over it with a different color. Once the paint is dry, they remove the tape to reveal a clean line between the two colors. The person repeats this process on all of their nails, creating a unique and colorful design.
