Porphyrophobia

Porphyrophobia (from Greek porphyros, "purple") is fear of the color purple. This a subclass of chromophobia, the fear of colors. Like all other phobias, including all color phobias, the original cause of porphyrophobia traces back to a traumatic experience involving the color purple in the past. Even though purple is the symbolic color of royalty, people can suffer from purple phobia quite readily due to a traumatic encounter that is not a very common color around. For example, getting hit by a purple car, resulting in serious consequences. Porphyrophobics would try to avoid seeing or encountering purple, and due to the rarity of the color, suffering panic would not occur that readily. Sufferers (especially those who had purple poison ivy rash) may associate purple with poison, readily causing toxiphobia.

Sufferers will avoid eating grapes, plums, eggplants, or anything purple.
