      That’s kinda up for debate. Most people casually consider violet to be purple, and the distinction of it being a non-spectral color is a (fairly contentious) academic one.

      Now pink, on the other hand, that’s an unholy creation not of earth…

        Violet’s wavelength is singular, and near the edge of the visible spectrum while purple has 2 peaks and is in the middle, as mix of red and blue (as stated). Think harmonics but with light.

        They are very much different colors. The shade/hue/etc. are all different values. 4F2F4F vs 800080.

          And yet if you tell someone to go get the purple flower over there, they will not be at all confused and know exactly what you’re talking g about. They may be technically different colours, but practically they are interchangeable.

            I get that, during casual conversation etc. But what if there’s a bunch of violet and purple flowers and they pick a violet one? The distinction can matter and knowing it can be useful. You can’t use other people’s ignorance as an excuse.

            Even crayon companies make both for a reason JS :P

              But what if there’s a bunch of violet and purple flowers

              If you only provide the color, regardless which one, there would be a high risk of them choosing the wrong because they are so visually similar. so you would of course provide further physical description that would help distinguish the correct flower.

        Not being spectral means it’s not a single colour, it’s always a mix of colours

          So lots of colours are a mix of colours. That is kind of the point.

            Yes, but also a bit of no. Some mixes produce the colour that is exactly the same as you would produce bulky a single colour. Statistically I would guess that most don’t, but I am not sure and failed to find such a statistics on the internet
