Hi Thomas,

According to the instructions, we need to create a a method named switchColor that takes a value of Color as an argument. Your current code looks as if you're trying to call switchColor, but we haven't defined that yet. So let's get the method declared, using the func keyword to define it.

For example, we might get rid of:

protocol ColorSwitchable {
    switchColor.Color(color)
}

And replace it with:

protocol ColorSwitchable {
    func switchColor(color: Color)
}

Hope this helps!
