The colors red, blue, and yellow are known as the primary colors because they cannot be made by mixing other colors. when you mix two primary colors, you get a 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”.)
