Challenge Program: Rainbow

Not every color is available in the Java API in the Color class, some colors must be made in a custom mix of red, green, and blue lights.

Have the Finch:

1. Announce that it can display all the colors in a rainbow (saySomething method)
2. Say each color as it displays the color on its beak.
3. Make the colors in the middle of the rainbow last at least twice as long as the ones on the edge.
4. Use at least 7 different colors including some custom mixed colors (here is a chart to help)
5. Say each word clearly, without running the words together (pause briefly between words)
