Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

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
