switch (BtnColor.BackgroundColor)
            {
                case Color.Red:
                    BtnColor.BackgroundColor = Color.White;
                    break;
                case Color.White:
                    BtnColor.BackgroundColor = Color.Blue;
                    break;
                default:
                    BtnColor.BackgroundColor = Color.Red;
                    break;
            }

i am getting the following error on: case Color.White: and case Color.Red:

A constant value is expected

Colors are not constants, and that's what you're supposed to use when using Switch statements.

Predefined Colors are Static Properties of the Color class, so that can't be used.

In this case you can use if/then/else statements to achieve the same exact thing.
