Answer 1

You don't have quotes around the values. The system is looking for the names of the colors as is they are variables.

For example...

You have: if(color==red)

Should be: if(color=="red")

Answer 2

Have a look at what the error message says: "The name red does not exist in the current context."

Where did you define the color variables?
