For Concetta Antico, the night sky bursts with sapphire and violet; a pink rose is tinged with gold and azure; a stone pathway is a rainbow of oranges, yellows, greens, blues, and pale reds.
Antico has “super vision,” or tetrachromacy, a rare genetic condition that allows her to see nearly 100 million colors. Compare that with the one million colors people with normal vision can see.
