You are creating a canvas app to enable users to order tickets. You create an input field for users to input the number of tickets to order.
Users must order a maximum of four tickets and a minimum of two tickets. If a user enters a number except 2,
3, or 4, the input field must display in red. If a user enters the numbers 2, 3, or 4, the input field must display in green.
You need to color the input field based on the user input.
