Why is it hard in the times where AI itself can do it to add a light mode to those blacks websites!? There are people that just can't read dark mode!
Models that take visual input seem more focused on identifying what is in the image compared to what a human might perceive is in an image, and most interfaces lack any form of automated feedback mechanism for them to look at what it has made.
In short, I have made some fun things with AI but I still end up doing CSS by hand.
