Ombre Nails are very eye-catching because of its color combination. From soft pastel Ombre Fade for the day to day, or Glitter Ombre Nail Arts for special occasions like weddings, baptismal, etc. And of course you can do Bold with a Rainbow Ombre effects
I chose this for rhythm because they are all the same drawing being repeated but the color makes the drawing interesting so you dont just see the same thing being repeated. Without the color it would almost be the same drawing repeated.
