When I was working on a team with an accessibility requirement. The bulk of the work wasn't coloring work, nor writing alternative texts, but ensuring that the website could be navigated well using a screen reader.
We used JAWS[0] and tested every change and new feature with it to ensure users of it could make sense of the website. This was a lengthy process that took a lot of effort and learning on the part of devs to pick up JAWS.
The tough part of it was it being a subjective process. No one can tell you if the final experience was "correct" or not.
This part of web accessibility isn't mentioned as often, but its just as important. Likely because not many people really know about it.
Edit: I think part of it is the high cost of products like JAWS. The current price of a home license is $1,000. A business license is $1,285.
