I would imagine it has to do with the retina where photoreceptors exist

/e all of the physical stuff has to do with magnification of the image (or incoming light) onto the retina

Yes, if you make the image big enough, looking at each ball individually it look brown, but the ones in the periphery take on their different colours.
