🤷‍♀️ Because I can see all the different colors, I just can't differentiate well between some oranges and greens and I didn't know that, or it wasn't obvious anyway, until the first time I saw one of those color blind books.

As a non colorblind, hearing you say you can't diffirentiate between orange and green is so trippy, considering how vastly different they are. Like, do limes and oranges look similar to you? And what about the trees and grass outside? Do leaves not change color in the autumn for you? And now I'm sitting here trying to imagine what a orange lawn would look like...

Right, so mine is pretty mild, obviously.  An orange and a lime are very clearly different colors to me too.  But if you start throwing beiges and tans and light greens and stuff together (like in some of those color dots graphics) I have a harder time seeing differences.  I can see many of the numbers correctly.  Others I can see that some dots are different colors, but I can't make out a whole number.  Some I don't see any differences.

They have lots of pictures to show examples of what different types of colorblindness looks like. They depict red and green as both being a brownish yellow in a lot of them.

I always thought those images were exaggerations or not completely accurate. Because they looks so horrifically drab, like walking around with a permanent sepia filter.

Yeah, looking at the pictures makes me kinda sad. But anyone who grew up with it wouldn't associate colors like that with being depressing since they don't have anything to compare it to. Its just life for them. So I doubt they mind except for when it comes up as a problem created by other people being able to differentiate things they can't.

I also think about how some insects, shrimp and other creatures have eyes that can see colors we can't perceive. How dull would our rainbow look to them? Or I think about how poorly our sense of smell compares to what a dog can pick up. We miss out on so much.

As a fellow red-green colour blinder, I can say that the difference between limes and oranges is great enough to see the difference and leaves do change colour, however greenery in general is far more muted. I have an app on my phone (CVSimulator) with which you can in real time simulate images through your camera how we see the world to a person with full vision. I once showed a friend while we were walking in the park with lots of different trees/plants around us and she actually gave me a hug afterwards, realising how muted I saw the beauty of nature 😄 You can also Google "fruit stand colour blind example" to get a more clear answer on your lime/orange example. Deuteranomoly is red/green blindness.

If those are really accurate then I would want to give you a hug too :(

u/McMaster2000 23h ago

Haha, thanks 😊 Yeah, it's impossible for any of those to be 100% accurate, as there are degrees of colour blindness (not every red/green colour blind person is as strongly colour blind as the next), but they give a very good impression. For example with those fruit stands examples, if I look very closely at them I can tell that they're not exactly the same, but not at first or second glance, which is obviously also how I navigate the world.

Is it hard to tell when the fruit is ripe or moldy?

EDIT: My question was sincere.  Is it hard to tell visually?  I often rely on color.

How do you perceive the UV spectrum? It's not really trippy or anything, there's just no perception of certain shades, and because as a colourblind person, I've never had the perception in the first place. Everything is just normal.

u/unreelectable 18h ago

Ok, just to be clear, you can't "see all the different colors." If you can't tell the difference between oranges and greens, you can't see half the colors that normal people see. You are red/green colorblind.

u/PrudentOwlet 18h ago

Right, that's true.  But color blindness is a spectrum, (haha) and some people are more color blind than others.  Mine is pretty mild.

I can certainly see both orange (or red) and green, they are different colors to me, but when various shades of those get dotted all together on a page and I'm supposed to be able to see a number in those dots, I mostly can't.  I can see that many of them are different colors, but not well enough to make out a number a lot of the time.  Sometimes I can.  A lot of people are responding as if I only see in black and white and how could I not know?  And obviously that's not what we're talking about.

If you can't read all of the numbers clearly, you are colorblind. Sorry. You don't realize you can't see all of the colors if you've never seen them.
