Did you ever wonder if the colors you see are the same colors that other people see? For example, when you look at traffic signals, do you see bright green, yellow, and red? Or do you only see green, light gray, and dark gray? We all have different eyes and brains, so each person’s vision is probably a little different, too. This is very true for people who have color blindness.
There are different types of color blindness. Some colorblind people cannot see a specific shade of color, often red. For other colorblind people, the whole world appears as gradations of gray. Often being colorblind is hereditary, but it can be caused by other things, too. Right now, there is no cure for color blindness, but there are some interesting machines that can help colorblind people see color.
