I guess it depends on whether you consider RGB(0,0,0) to be on the same spectrum as RGB(100,0, 100) or RGB(100, 150, 100).

RGB(10,10,10) may be awfully dark but it's definitely not black. On the spectrum doesn't necessarily mean you have clinically relevant difficulties.

The more helpful way to think about is that the neurotypical brain is like RGB(63.32, 12.3, 73.02) but with thousands or maybe millions of variables. If certain values are significantly lower or bigger it might cause you trouble.

Having Autism is one cluster of values you can have. So is having ADHD. So is having Trauma. And many more things. And you can and often have multiple things at once and their symptoms overlap.
