The rgb color model is not to be used in science or philosophy, it's useful in computer science because monitors are RGB.
Take a look at the LAB color model. It's defined with three axes; lightness, green–red and blue–yellow.
Yellow has no special meaning in this model.
- majewsky 9y agoThe RGB color model has its origin in physiology, to match the three types of color receptors in our eyes. (The LAB color model also originates from physiological considerations, but on the neurological level, i.e. at least one step after the color receptors.)
- rcxdude 9y agoRGB doesn't really match the color receptors though. The cones in your eyes are more like 'blue', 'yellow-green', and 'yellow-red'. RGB is just a convenient way of covering a decent amount of the color space we can perceive.
- majewsky 9y agoThat's why I used the fairly broad "has its origin in".
