It would have made more sense if they had shown the distribution of hue as a polar graph and just had one every decade to show how it changes over time.

I wouldn’t trust someone who tried to visualize hue like this to make that calculation correctly.

Value is essentially luminance.

I think that a step in the actual right direction would be forcing platforms to give people actual ownership of what they pay for. If they have a licensing issue and want to pull the game, they can stop new sales, but they shouldn’t be allowed to make it unavailable to people who’ve already paid unless the entire company is going under and the store is shutting down (and even then, they should be forced to provide non-DRM downloads).
