Why am I seeing the wrong colors?
People who are totally color deficient, a condition called achromatopsia, can only see things as black and white or in shades of gray. Color vision deficiency can range from mild to severe, depending on the cause. It affects both eyes if it is inherited and usually just one if it is caused by injury or illness.
What does Tetrachromatic vision look like?
If you see between 33 and 39 colors, you are a tetrachromat and have four types of cones. Derval says tetrachromats are irritated by the color yellow but are less likely to be tricked by the blue/black or white/gold dress, no matter the lighting. Only about 25 percent of the population is tetrachromat.

What is it called when you can see more colors than normal?
This is called the theory of tetrachromacy. While trichromats can see about 1 million colors, tetrachromats may be able to see an incredible 100 million colors, according to Jay Neitz, PhD, an ophthalmology professor at the University of Washington, who has studied color vision extensively.
What triggers kaleidoscope vision?
Kaleidoscopic vision is most often caused by a type of migraine headache known as a visual or ocular migraine. A visual migraine occurs when nerve cells in the part of your brain responsible for vision begin firing erratically. It generally passes in 10 to 30 minutes.
