No. #2 is bad analogy and the way you are describing is misunderstanding of what ASD means as spectrum. It is not RGB, but more like list from tens of different diagnoses - probably ranging to 20 or 30 in number, so more than 4, that colors are offering and that also means more dimensions, but could include more, that some people manage to get as some kind of collection - some people have collected nearly 20 of those to illustrate the problem, that people diagnosed with ASD are similar but at the same time different in their own way. Another issue is because of ASD you do not get to collect other Autistic-related diagnoses, that would narrow your condition.
On top of that, if you have ASD diagnosis, you definitely have other issues that describe your condition more, especially mental issues. Also, some of them are going to change - some can go away, because environment changes or simply because your understanding of issues have changed. A lot of the struggles are because diagnosed people even after diagnoses do not understand what exactly they have to deal with.
The issue is how these conditions are diagnosed - there are some similarities with LGBTQ+ that initially was labeled as a disease. And there is cautious fluidity in labeling because of that as well, because ASD is not completely understood, as we are really in the very beginning on mapping both of our brain functions and DNA - what those genes are responsible for. Also, the number increase of ASD might have other factors involved in the way how we as modern people are using our brains by dealing with all that information that humans previously did not need to do and most probably ASD is species wide change that we are causing as our behaviour has changed, especially when our unwritten beaviour rules are breaking down. When we have to compare this to how species are described, humans alone would be consisting of different species - the only difference why we are not different species is because of mixing.
