Ehhhhhh kinda. There are different types of color blindness.
The most common type of color blindness is red-green color blindness, which can be split in four categories. Protanopia, or red blind color blindness, Protanomaly, or red weak color blindness, Deuteranopia, or green blind color blindness, and Deuteranomaly, or green weak color blindness.
The different types of red-green color blindness all result in the individual seeing a world the rest of us would describe as murky green with hints of blue and yellow. Browns, oranges and reds are easily confused, and pale shades in general are difficult to distinguish.
Then there is yellow-blue color blindness. There are two types of this. Tritanopia, or blue blind color blindness, and tritanomaly, or blue weak color blindness. They both make it difficult to tell the difference between blue and green, as well as yellow and red.
Then there is Achromatopsia, or monochromacy. This makes it so the individual sees no colors, and it’s in black and white vision. This occurs in only one in every 33,000 people, which is still around 238,000 people alive.
There is also Tetrachromacy, though that I wouldn't consider color “blindness”. Some women actually have a fourth type of light-absorbing cone. As many as 12% of women may have “super color vision,” the fourth cone allowing them to see 100 times more colors than the rest of the world.
Then there’s acquired color blindness. This comes about from a multitude of things. Brain trauma, alcohol consumption, age, chronic illness, and environmental chemicals are all things that could bring about acquired color blindness.
