In the video, a person is seen coloring a picture of a unicorn with a blue marker. The unicorn has a purple mane and tail, and the person is coloring the mane with the blue marker. The person's hand is visible, and they are using a back-and-forth motion to fill in the color. The marker appears to be a thick-tipped permanent marker, and the color is a vibrant blue. The unicorn's mane is already partially colored, and the person is adding more color to it. The background of the video is not visible, and the focus is solely on the coloring process.
