I don't think that's it. Open https://tailwindui.com/css/app.css https://tailwindui.com/css/app.css and Control-F for "placeholder-" -- are there really examples and component pages on this website that set the input placeholder text color to every single different color in the color palette, at every responsive breakpoint?
