There are three types of color receptors in your eye: red, green and blue. But how do we see the amazing kaleidoscope of other colors that make up our world? Colm Kelleher explains how humans can see everything from auburn to aquamarine.
Talk by Colm Kelleher, animation by TED-Ed.
ALLAH is great
i love that our eyes are seeing this and knowing that this is happening while we're watching this
First I always think the natural world is beautiful. But in a way, the act of us learning something is just as beautiful
While I knew all of these things, I always have a hard time explaining and you guys are doing an awesome job at it. I think from now on everything I speak to someone about colours the eyes I'm just gonna show them this video instead. Keep up the good work!! :)
this fascinating! but then I started to wonder... what if someone genetically engineered a people with retina cone cells for other light waves? like ultraviolet or radio waves. would those guys think the rest of us color blind? and how might their perception of color be different from ours? Makes you think doesn't it?
lol, Its an Irish accent.
He sounds so happy. :D
seeing this makes me want to protect my eyes more
A nice, concise, and simple explanation of a complex topic.
This is one of the most fascinating video I've ever seen. Proves how little I know. Thanks!
RGB is an additive color system, where the colors combine together at the same time.
Red blue and yellow form the basis of a subtractive color system. Each dye works by absorbing colors, but reflecting a certain frequency well in order to give it its color. When you combine them, the two dyes each absorb some of each others frequencies, which causes them to reduce the strength of the two.
The primary colors in each are really determined by several things and I don't have room here for it.
Beautifully and lucidly explained 👌
Ahhh, the 'no signal' tv screen with that specific array of colours... It all makes sense haha!
Yea, you made my point clearer and more concise than I did, hadn't thought about the "cross wiring" with other sensations of which there are many examples now I think about it!
I like hearing voice artists with a variety of accents. Addison is good, but I'm happy to hear the diversity of others.
Ted-Ed videos r equal to ASMR videos for mee,so relaxing ...😌 (additional benefit: no wastage of any products and u get to know about something in detail)
Thank you so much for your videos. I find them very helpful; I have an exam in perception and cognition, and your videos are extremely helpful! Thank you!
good video, nicely and concisely explains certain aspects of colour vision in humans.
Finally, It took me some time to find a show that understands why we really see light. I give props to Colm Kelleher's internet science show... I feel you should get the nobel-peace prize but maybe some day...
Animations are WOW really playing a big role in understanding and learning. 👍👍👍👍👍👍👍👍👍
Wow, I'm used to working with RGB stuff in photoshop and video editing software, but I honestly never knew why these three colours are so important. Thank you so much for clearing that up, it totally makes sense to me now!:)
