Maybe if you tried a community of 100,000+ UX specialists, you would gain some surprising insights. If only such a community existed somewhere...
PS: If these buttons serve as an accessibility solution, I wonder which accessibility guidelines you are following. It appears that those of us who actually work in accessibility use something different. Moreover, visual accessibility is not the sole type of accessibility that exists. I highly doubt these buttons pass most neurological accessibility tests and they will probably fail at quite common conditions like Autism and OCD. Show this
to someone with OCD (and many autist people) and see the world burn. (thank you @wizzwizz4 for the image)
EDIT: Any UX apprentice knows that the image below is a perfect example of cognitive overload. It is typically taught at the early stages of one's career.
