The colors red, blue, and yellow are known as the primary colors because theycannot be made by mixing other colors. When you mix two primary colors, you geta secondary color:When you mix red and blue, you get purple.When you mix red and yellow, you get orange.When you mix blue and yellow, you get green.Design a program that prompts the user to enter the names of two primary colors,one at a time. If the user enters anything other than "red," "blue," or"yellow," the program should print "You didn't input two primary colors."Otherwise, it should print something in the format:"When you mix red and blue, you get purple."(Assuming the user entered "red" and "blue".)
