Why we're blind to the color blue... we'll explore why our eyes are unable to focus on the color blue, and how we see with our brain as much as with our eyes
10 projects - #6 - why we're blind to the color blue
project goal - I'm always in the market for surprising facts. One of my favorites is that the color blue is always out of focus for the human eye. It's hard to believe since it appears that we see blue clearly, but it's astonishing when shown an example. Here', I'll explain why we're unable to focus on blue, and show examples of what it means for image sharpness.

Conclusion: Our brain extracts some color information from the blue channel, but delegates sharpness to the red and green channels which are in focus. The result is so astonishing, that I have to wonder if there is something that may go awry from modifying and displaying these images on a computer.
