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”.)
