Oddly enough, I'm colorblind and I have had the worst time with color schemes. Many are completely unreadable and lack sufficient contrast. Others I just don't like
So, I've started using AI models to generate color schemes for me.
Take an unreadable theme I like and generate one that is high contrast and still coherent. It's probably not good enough for a full spectrum vision person to use but wow has it improved my quality of life.
It wouldn't surprise me if this is exactly the type of problem that is solved in the same way for the rest of you
