Hey Shane,

The challenge is asking you to create a protocol that has one requirement: a function named switchColor that takes a parameter color of type Color. To do this, you should declare the protocol as follows:

protocol ColorSwitchable {
  func switchColor(color: Color)
}

Hope this helps, Rodrigo
