Why do some colors share the same hex code?

HTML/CSS defines both Aqua and Cyan as #00FFFF, and both Fuchsia and Magenta as #FF00FF. They’re distinct names for identical colors—a quirk of the CSS specification.

Can I use these color names in CSS instead of hex codes?

Yes. All 140 named colors are valid CSS color values. Write color: tomato or background: steelblue and every modern browser will render them correctly. Named colors are easier to remember but hex gives you access to the full 16.7 million color range.
