Medical Color Resolution in the Eye (blue and yellow)

  1. Jul 14, 2008 #1
    I'm having trouble finding information on why when you get far away from a piece of paper covered in yellow and blue dots (evenly spaced) the sheet eventually appears green. I know this has to do with color resolution but not much beyond that.

    Here's something a bit interesting and somewhat related.

    There is a matter of the Rods and Cones, their sensitivity, and their placement in the eye. Our brain has a tendancy to fill in gaps aswell, smoothing the perceived information. Have you noticed that in the colour specrum there is no such colour as brown? From what I have read it is the product of a conflict in perception of the colours red and green The input signals don't mix well so our brain creates the colour brown.
