Lecture 20: Introduction to Color Science (Cont) (51)

Wolfram alpha has an interactive chromaticity diagram here (https://bit.ly/2Vt0nEM). You can alter things such as the color space, gamma values, the type of plot, and a variety of factors. It's a very friendly hands on way to understand the chromaticity diagram better, and I found it a more comprehensible description than just a 2d figure.

Professor mentioned in lecture that any point on the same line through the origin (I think he's referring to a ray from the origin) would be the same color with different brightness.

I'm curious about that why can't we choose a different set of basis colors so that more colors can be displayed. Or, why is RGB so special in color display.

I'd imagine that you could get a wider color gamut by adding another subpixel color to each pixel on a monitor. But of course that increases cost per pixel/mm^2, probably pretty dramatically. So there's an incentive to minimize the number of subpixels per pixel on displays.
As for why RGB, it looks like these wavelengths align best with human photoreceptors?

Not only cost in space, you would also need to consider how information formats would need to be expanded!
