Rainbow - Can you create it?

Combina los colores del arco iris para crear la gama de colores que lo compone!

Combine the colors of the rainbow to create the full range of colors that make it up! Seems easy? You are wrong!

In this version there will be no numbers to help you, only the basic colors that make up the rainbow will help you solve it.
