What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

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

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



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

Your post 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.

Posts and comments 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 non-TIL posts.

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



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.



Rule 10- Majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

I want to better understand this because the sky is clearly a specific color that has been there since the beginning.

How did proto humans not look up at the sky and considered in their feeble brains, "everything above the ground is this very unique color. It's different from the ground, and the plants."

I get that sea and lakes really don't look blue. But did they look up and not see some shade of blue on a clear day?

My understanding is that they don't distinguish blue and green as separate colours. Kind of like pink is just light red and not every language has a separate word for pink and red.

I'm here for this, I recently found out that I can't really distinguish shades very well, so pink just looks mostly red and I have a really hard time telling blue from green, but can usually make it out if I look hard enough and get at least 2 guesses.

Either that or my wife got my doctor in on a really intense year long prank.

I think I have this same issue with red/pink and when a color is one or the other in that in-between area. I also do this with blue and green as well, though I feel less so than pink/red. I also have done colorblindness tests myself and do not test as colorblind (either variety).
