This is really interesting. They colorized a photo by overlaying some lines in a grid and ONLY adding color to the lines but oversaturating the color. The rest of the image is black and white.

The result is that at a distance or in the thumbnail it just looks like an ordinary color photo. It is only when you look up close you notice what is going on.

@freemo this is fascinating. I wonder what inspired this idea.

It's common in image compression to down-sample or dither color, as it doesn't affect our perception much. This seems like an exaggeration of that. The things our eyes would to to keep us sane are just insane.

@Liberonscien It was in a study i read a while back and honestly cant remember the details. I found it hiding on my system from when I shared it on facebook a while back.

@freemo @Liberonscien most interesting. Particularly that the blue and yellow respond to the treatment more effectively than the red.

Would also be interested to see how it goes with non-primary colours and patterns. Certain the image selected is one which lends itself well to the experiment.


There are some non-primary colors used int he image as well.

I do find it interesting that red behaves differently, though not surprising. Our eyes do tend to notice red more strongly than other colors.


@freemo I wonder what this would look like to the people with the different kinds of colour blindness?

@freemo appears as if functionally comparable to RGB pixels in how they appear to be a singular color, although on a different scale. Less so on our modern high DPI monitors, but on older monitors with lower DPI, I wonder if it is comparable
