Ohhhhhhhhhhhhhhhhhhh
What do colorblind people see? Any color blind people out there?
Polar bears
Brain working as expected. Thank you for the confirmation. I did have some doubts before.
From the thumbnail I just see polar bears with tiddies.
Fun fact! Since we (primates) have three cone cell types, we only really see three colours (red, green, blue). The rest are illusions. Some animals, like some fish and birds, have four or five cone cell types.
This means that for animals that have a cone cell type for yellow, a sunflower displayed on an LCD screen will not have the same color as a real sunflower. The screen will show a mixture of red and green (which we perceive as yellow) but it won’t actually be yellow.
Mantis shrimps seem to be the champions of this. They have between 12 and 16 different types of cones, spanning into the ultraviolet. They have a very different visual processing system to most animals though, so despite all the cones, they don’t seem to synthesise shades between them, so they probably don’t have a very vivid image.
It’s more complicated than that. Colours are not some discrete things, it’s a spectra. Even one colour is a bunch of wavelengths.
So in truth each eye cone of ours perceives a spectrum.
But real sunflowers are (and correct me if I’m wrong) yellow colored, so why LCD screens don’t do tue same thing? Is it because they are based upon RGB? If so, that kinda feels like an issue with screens and not with our lack of cones
Yes! We developed screens to suit our eyes. Pixels look like this: https://b2c-contenthub.com/wp-content/uploads/2022/04/subpixels-monitor-types.jpg
It’s not an issue, it’s just that they’re built to be viewed by three-cone creatures.
Obligatory “there is a Radiolab episode about this”: https://www.radiolab.org/podcast/rippin-the-rainbow-an-even-newer-one
And here is a great video by Steve Mould about cameras and true color: https://m.youtube.com/watch?v=-DyrBDsKA5s
Just spit ballin’: The TVs don’t have “yellow” cuz we don’t have the cones. TVs are built by humans for the use of other humans. Why would we design them to produce light that we don’t have the cones for?
If we all only saw black and white, we wouldn’t have developed TVs with color. If we were all blind, we wouldn’t have developed TVs at all
Edit: I think this has interesting speculative fiction implications regarding technological development, especially in scifi
I’m no polar bear but I don’t think the seeing happens in the brain.
But it is. Eyes just receive light.
okay, but why are they Wanda and Cosmo colored?
If I had a nickel for every time somebody asked that…
I’d only have one nickel.
… but it’s a girl nickel!
I remember when I learned about the possible existence of a girl nickel. It was right before creating this reply to it.
Its such an absurd joke, its my favorite stupid joke in the entire show.
Its uh… ‘pizza the hutt died of eating himself to death’ levels of just ridiculous.
Good question! Some people will probably cite the electromagnetic spectrum, but in this case the scientific principle is much simpler. It’s called “because I felt like it”
funderstandable, have a nice day
Colour is just an illusion caused by objects absorbing some frequencies of light and reflecting others into the photo receptors of your “eye”.
Oh my god this is so stupid but I love it!
Got an actual belly laugh out of me, oh god, I’m crying… thank you OP.
And magenta is a lie Dx
No, this must be an illusion. All ice bears are white, even albinos
Stupid brain.
Gummy Bears’ new shape is pretty detailed
