> Colors should be good to go if the website is well-styled to begin with.

What if it is not well-styled? Or, maybe some people think it is and others disagree and want something else. The end user should need to customize fonts (not only larger, but also if you want smaller fonts; I more often find the fonts on a web page are too big and want smaller fonts; however, also you might prefer a specific font typeface and not only the font size), colours (also for many reasons, including using a monochrome display or printer that the web page author might not have been aware of), animations (e.g. to disable them), margins, etc.
