This is a very short video I thought interesting
The reason I went looking for YouTube videos on color vision early this morning, is when reading a thread about deep red laser diodes, I was mulling over the reality of color vision, how colors don't really exist at all except through our eyes ability to allow the brain to distinguish some of the different wavelengths of light, as a genetically provided sense phenomena. I knew this, but for some reason the reality that colors don't really exist as we perceive them, except in us, became clearer. After that, I stopped thinking of color and started thinking in reference to wavelength alone for a few moments, finding I much prefer our colorful world over the cold reality of wavelengths, snapping back to the shared but colorful illusion of RGB and everything it can provide; millions of possible perceived variations, some colors such as magenta which as far as the R,G & B sensing cones of our eyes are concerned, don't even exist in relation to a wavelength except in our mental constructs of combined frequencies. Pushing further into thoughts about wavelength it occurred to me how we hear sound, it too is only differences of wavelength yet I hear pitch, of course sound is not perceived like we sense colors, but hearing is also a sense phenomena and except for amplitude and mixes, only a difference in wavelength. I'm up in the arctic again baby sitting some telecom gear, I guess I have too much time on my hands if thinking of such things.
Another YouTube I found interesting about color mixing:
Watch this video and it will auto-start another of the series which I find even more interesting.
