Well I agree our perception of 'colour' is a reasonable discriminator of colour (or at least photon wavelengths) . That was never an issue.

Sorry, I'm lost. I don't know what you are asking.

In this post I was not asking anything. Just agreeing that our vision has a reasonable colour discrimination. And also pointing out this was never an issue at least not for this thread.

So this whole thing started when I claimed, much as the gentleman in your video, that colour was an illusion.
