Problem

Star saw a machine with a star inside it. He could not look inside the machine, so he could not see the star directly. The machine had a dial that showed the wavelength of the starlight. Using the wavelength on the dial, Star worked out the color of the star. What color was the star?

The wavelength ranges for each color are as follows.

Red: 620nm or more and 780nm or less
Orange: 590nm or more and less than 620nm
Yellow: 570nm or more and less than 590nm
Green: 495nm or more and less than 570nm
Blue: 450nm or more and less than 495nm
Indigo: 425nm or more and less than 450nm
Violet: 380nm or more and less than 425nm

Input

The wavelength $\lambda$ of the starlight shown on the dial is given. The wavelength is always an integer, measured in $\textrm{nm}$ . $(380 \leq \lambda \leq 780)$

Output

Print the color of the star. Print "Red" for red, "Orange" for orange, "Yellow" for yellow, "Green" for green, "Blue" for blue, "Indigo" for indigo, or "Violet" for violet.
