I can confirm that I see both an orange car and a 21. I'm not colourblind in the "I can't see any colour " way and I can drive a car and see traffic lights without any problem but I do percieve colors differently enough to get in arguments with friends and family about the colour of stuff. I think it's called deuteranomaly
Edit :the more I know!
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!
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?
It does include purple, it's a little bit before the 400nm mark.
You are actually textbook definition of colour blind. What you have is deuteranomaly which is red green colour blindness.
So is it white/gold or blue/black?
Even though I know the dress factually is blue and black, I think a white and gold version should be made, because it's pretty.
And it should also be photographed in such a way that it appears to be blue and black.
