All human color technology - paintings, photographs, screens, lighting - is optimized to stimulate the three types of human retinal cone cells. The exact sensitivity of each cone type to light across the spectrum is not even as important as the relative levels of activation of the three cones by the light. Which is why when some light activates 100% of “red” cones and 100% of “green” cones you see it as yellow, regardless of whether the light is a broad-spectrum light from an incandescent lamp or a single frequency 575nm LED light. This is also why only 3 numbers (0-255, 0-255, 0-255) is enough to describe every color that humans can ever see.

Other animals can have different number of types of cone cells, and the light-sensitive pigments in them can be slightly different from human ones, having different spectrum response curves. Bees in particular can see ultraviolet light, and flowers have designs on them that can only be seen in UV, specifically for bees.

An arbitrary photograph will not appear color-photorealistic to other animals the way it does to us, but animals can still see shapes in it and identify objects, the same way you can recognize people even in a photo-negative.

!nostupidquestions is a community space dedicated to being helpful and answering each others’ questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All posts titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That’s it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it’s in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.

Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.
