Can colour-blind people see rainbows?

Answer 1

First let me address what I *think* you're asking. If you look at a black and white photograph of an rainbow, despite the fact that there is no color information in the picture, you will still see the arc. That is because different colors in the light spectrum have different saturations - they are more intense than other colors. So that in black and white, some colors look darkers while others look lighter. This is an intersting problem faced when making "maps" for rodents in a behavior lab, for instance. They see no color, so adjacent color block landmarks must be different saturations, otherwise it all looks the same to them.

Now, it is a misconception that color blind people see the world in black and white. This isn't true for the vast majority of people who suffer from color blindness. They typically just can't distinguish between a few color. The most common kind is red-green color blindness. In this disorder (mostly affecting men, as it is an X-linked trait), red and green are nearly impossible to distinguish. Indeed, the old gold-standard test for this is a field of red dots with a vague number or letter written in green dots...people with normal vision can immediately spot the figure, people with R/G disorders cannot.

So, in conclusion, yes, most color-blind people will see a rainbow. They may miss a few of the colors, but they will know its there, and they will see some of the colors.

No - colour blind people can't see anything that has a colour. It would be invisible to them.

Answer 5

some times. there are different types of colourbline, some people see in black and white, whereas other people just have trouble seeing colours like red and green and i think blue. this is why if you have your eyes tested, they test you on those colours, like "Which is more clearer, the green, or the red."

Answer 6

I think they would see something similar to a black and white photo. So even though they dont 'recognize' the actual colors, they could tell them from eachother. Good point also, Irish Princess :)
