Color Vision Model

This modified FFD model shows how photoreceptors and neurons can be connected to process color information. The model explains familiar color experiences, like color mixing and color space. There is no other explanation of even one color phenomenon.

Unfortunately, Adobe and the major browsers stopped supporting Flash Player at the end of 2020. 

You can request a copy of the Flash executable .swf file that I created by clicking on Contact Us.  To see what you will get, take a look at the Color Vision > Videos on YouTube.

The file requires a Flash Player, and the .swf file can simply be opened.  If you don't already have this, it can still be obtained.  There are many players available, and I highly recommend Ruffle. I used it to make the YouTube videos. It's very easy to download and to use. See here for other suggestions. If you have any problems, let me know.

Here are several depictions of the model.
