    Post Why we're blind to the color blue...

    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.

    If it wasn't for Army green, blue would be a favorite color.

    I'm going to have to play around with different colors on my computer screen. I always use shades of blues.

    I grew up in a household of graphics and photography. It's always interesting to read up on what the eye can see versus a camera lens, and how to adjust for it.
