Brain working as expected. Thank you for the confirmation. I did have some doubts before.

What is “color”?

Baby don’t hurt me,
No more.

It’s what happens when you spell “bolor” with a K.

karl’s koloring korner… actually it seems best to knever spell anything at all beginning with a “k”, ya’now?

No, this must be an illusion. All ice bears are white, even albinos

From the thumbnail I just see polar bears with tiddies.

What do colorblind people see? Any color blind people out there?

Polar bears

I’m no polar bear but I don’t think the seeing happens in the brain.

But it is. Eyes just receive light.

Fun fact! Since we (primates) have three cone cell types, we only really see three colours (red, green, blue). The rest are an illusion. Some animals, like fish and birds, have four or five cone cell types.
This means that for animals that have a cone cell type for yellow, an sunflower displayed on an LCD screen will not have the same color to them as a real sunflower. The screen will show a mixture of red and green (which we perceive as yellow) and NOT 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.
rockerface@lemmy.cafe 3 weeks ago
They basically have most of visual processing offloaded to cones because of how simplistic their nervous system has to be.
Viceversa@lemmy.world 3 weeks ago
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 spectre.

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
404@lemmy.zip 3 weeks ago
Yes! We developed screens to suit our eyes. Pixels look like this: b2c-contenthub.com/…/subpixels-monitor-types.jpg
It’s not an issue, it’s just that they’re built to be viewed by three-cone creatures.
Here is a great video by Steve Mould about cameras and true color: m.youtube.com/watch?v=-DyrBDsKA5s

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 black and white. If we were all blind, we wouldn’t have developed TVs at all
