Wow, this is the least wrong video on color spaces I've seen! But seriously, I've seen so many just completely wrong explanations of cones and XYZ that to have a correct so far as I can tell video is very impressive. Honestly, this is a very difficult thing to explain, and you don't even have a good way to visualize a lot of it. I would have liked to see the gamuts in Luv or whatever to show the perceptual difference better, but the radial gradients were a great way to show the difference!
I discovered Lab color in Photoshop probably 20 years ago and have gripped tightly onto it. I always hoped more applications would adopt it. Of course now there are even more accurate human-friendly color spaces like HSLuv and the brand new OKHSL. But I digress. CSS transitions in Lab are going to be *awesome*.
I have enjoyed you doing the clap as well :) Also thank you once again. This is really exciting news! I'm really looking forward to being able to use L.A.B. in web design now.
Ok I had no knowledge about colors before watching this video and my current knowledge about colors is just like that negative frequency in that graph. LOL.On other side why does surma always choose topic like these that are more inclined towards math and able to go so deeper into such things. Is he a PhD in math?
@@AndrzejPauli yup it is now I am reading a lot about it already. The only problem is I am sure surma will be dropping part 2 next week I doubt if I will able to cover in order to understand part 2 😄
LCH is the same color space as LAB, just from a different perspective. LAB is cartesian (the space is a cube) where a and b have different colors at their extremes, while LCH (Lightness, Chromaticity, Hue) is cylindrical, and Hue is an angle, so it’s an cylindrical space. It’s the same difference as rgb() and hsl(). Same space, different coordinate system.
I don't understand why the primary colors don't exist in a space. They are just wavelengths right? They were mixing 3 wavelengths to color match. So the correct wavelengths don't exist? So you're telling me a specific wavelength doesn't exist?
That's part of what Surma was talking about: compare the CIE 1931 xy diagram against the later attempts at perceptually uniform diagrams such as CIE 1976 Luv: en.m.wikipedia.org/wiki/CIELUV#/media/File%3ACIE_1976_UCS.png
Fun fact, women could have more color receptors, so totally subjective interpretation can be happening and disturbing triangle math. Maybe that's why the salmon color was born ;-)
