    They’re still rgb plus maybe yw using colour mixing, so depending on the quality, tuning, physics and our perceptionof light, not all colours are as nice or bright.

      Yeah. I just think being RgB it would be good at purple 😂 One of those situations where the name was probably not created based on logic lol

        It’s called RGB because there’s a red, green, and blue diode. Not sure how that’s not a logical name.

          Oh I was making a joke cause it sucks at purple. Which is red and blue combined generally. But that’s not really how the RGB color cycle works as far as I understand in some extremely cursory Wikipedia reading lol

            IIRC, it has something to do with the fact that purple sort of doesn’t actually exist. As I understand, purple is basically your brain going “idk wtf it is but it’s not green”

                Right there with you.

                More specifically, it’s because purple fires your red and blue cones, but not the green one. Normally, as green is between red and blue, anything that would trigger those two also would trigger green. So when it doesn’t, that’s when your brain goes “well I guess it’s not green???”
