What is color? - Colm Kelleher

Have you ever wondered what color is? In this first installment of a series on light, Colm Kelleher describes the physics behind colors-- why the colors we see are related to the period of motion and the frequency of waves.

Lesson by Colm Kelleher, animation by Vitreous.

The graphics on this video were amazing, I love the geometric style.

I was exactly looking this information, thank you for making it so simple. Excellent video.And for all the people who are claiming that this is a bad video, consider the title. It is called "What is color?", not "How do we see color?". If you are looking for that one it is right there on the suggestion box, made by the same person. Learn how to look.

Love the animation. Looks very professional and is, in my opinion, way better than the 2 dimensional animations seen so far in your videos. I'd love to see you keep up this kind of animations for your videos! The better the visuals, the more enjoyable and easier the learning experience is!

[TEDEd]

Great question! We have a video coming out soon that explains that very idea - so stay tuned!

[brandonchristian]

I seriously don't understand why there are people who hit the dislike button on TED-ED videos. Like, really? it's educational, why you gotta hate?

[JohnnyJackPompolla]

I loved this video, the animations were sweet and explained everything very well!

[johanliebert]

what if we all see different colours as we cant explain colours

[RafaelReyesofficial]

This is by far the best animation i've seen in Ted ED.

This is way more interesting and fun than the boring physics class I had when I was a kid.
This is how lessons should be taught! Fairly intuitive and easy to remember.

I don't think anyone could make it better. What a beautiful video...

Some time ago, in a Gilmore Girls episode Lorelay says that her now grown daughter asked as a child "what is color?" and i couldn't stop thinking about it, thank you for the information.

[jiberish]

Fun fact about "color".
It comes from older words that used to mean 'a covering', 'to hide or conceal', which later became just the cover.
I find that interesting that it's related to words used to describe that which prevents one from seeing the inside of something. :)

[ktlyn]

"Colour" is also spelled that way in Canada, taking on British spelling of Colour :)

I'm so glad TED started making videos.

[SenorFabio]

one of the best animations ive seen! i loved the 3 dimensional block-y-ness of it. super coolio.

[isaaciw]

Are you kidding me?? I think this is a great video! I never understood what frequency was, and now Iv'e learned a lot more about color than i knew.

[xthatoneguyx]

it feels like this is just the tip of the iceberg....I HAVE SO MANY QUESTIONS!!! lol awesome video yet again. i loved the animation

[OhRishtopher]

Really liking Vitreous' animation. Looks so awesome.

[ErisNotEros]

I love the style of animation in this one
