I do not remember that comment, I should stop redditing before bed.

I feel describing cones by the colors they pick up makes it easier for people to understand. Not sure what was going through my head when I said rods though, I referred to them correctly earlier in the comment.

I would actually like to see monochromatic violet next to red and blue to see if there's an actual difference. Its not exactly possible to imitate this experiment with a screen.

Well, it's pretty clear that if my monitor has three leds, each one emitting light at different frequencies, the only thing that they can produce is the sum of lights at those frequencies, not another frequency.

And viceversa: there are colors that come from mixtures of frequencies and you cannot have with one frequency (purple).

Having said that, we only have three types of receptors, and it is possible to match the response of those as good as possible.

The premise is fine. I've seen sites like this before. However, if you want to invoke honest discussion and change, there should be a way to invoke nuance into the questions like "Should abortion be allowed?" By having a sliding scale (1-10), you have indications of that but not the information of why it's not a binary decision. Same with gun ownership and other questions - while you say it's a voting site allowing for nuance, there isn't feedback on why it is beyond a Positive-Negative graph where we would start at neutral.

Fun fact, its only due to a weird quirk of biology, an imperfection, that red and blue make purple. Were it not for this we would have a completely different color wheel.

The cone that picks up red also picks up just a bit of violet. So if something triggers both our red and blue rods, it must be purple. Our eyes cannot tell the difference between a single wavelength triggering red and blue and 2 wavelengths triggering red and blue, it sends the same purple signal to our brain either way.
