Viewing channels in color

- [Instructor] Alright, after that initial look…at color channels, it may seem downright peculiar…that the one thing that these channels are not is colorful.…After all, if you view any one of these…channels independently, whether it's the red channel,…the green channel, or the blue channel, you're gonna…see what is essentially a grayscale version of the image.…And there's really no way to reconcile the notion…that somehow, three grayscale images mix together…to form the full color composite.…It might seem even stranger when I demonstrate…that if you view two channels together,…you once again see those channels in color.…

So for example, if I click on a blue channel,…to view it independently, and then I also…turn on the green channel, then I'm gonna see…how these two channels mix together.…But, if I turn the green channel back off,…then I once again see that grayscale blue channel.…Same thing happens if I turn on the red channel…while the blue channel is also turned on;…then we're gonna see how these two channels mix together.…
