Three women, Lady Red, Lady Yellow, and Lady Blue, are at a clothing store waiting for their orders. While talking, they were interested to hear that one of them had ordered an orange dress, one of them had ordered a purple dress, and one of them had ordered a green dress. "Isn't it funny," asked Lady Red, "that each one of us ordered a dress with the color that is formed from mixing the color of our name with the color of the name of another one of us?" "I agree," said the lady who'd ordered the purple dress. Which lady ordered which dress? (Explain your reasoning.)
