Colourblind isn’t the complete absense of colour, e.g. everything looks black and white. With deuteranomaly, you are the actual textbook definition of colourblindness… There are different levels of it, but all can still perceive colour - it’s just whether the difference in colour of the spectrum is detected correctly.
Deuteranomaly (/ie) is the reduction in reactivity of the red-colour receptors. That means your perception of orange/red/brown is less than those with normal vision.
For those with normal vision, this is a great chart.
But, if you’re colourblind, it’ll be more confusing for you, sorry!
If I were to guess, it might be because purple isn’t a wavelength of light, it’s like a glitch in how we perceive light with the two cones opposite to each other in the spectrum being stimulated at the same time without the middle one.
For any practical purposes in every day life, purple is a color, it just doesn’t exist outside our perception.
So everyone can see a form of blue, most being royal blue? That’s super interesting because there’s a saying in art, “If you can’t make it good, make it blue.”

Why does the chart not include purple?

Suddenly, the 40k meme of purple orkz not existing gets a whole new meaning
