> Having a tool to provide a name instead of an hex code is useful to discuss colors with other stakeholders (customers, colleagues, etc...)

But how useful are names that this website shows, e.g. the first few random names I got were "Singapore Orchid", "Scented Spring", "Lamiaceae", and "Lunatic Sky Dancer"?

I provide all kind of name lists. Depends a lot on what you are trying to accomplish. But there are plenty of lists providing more recognizable ones.
