This is nicely done, but can you please explain why you need this? What is the use of the color names when you already know the actual color value and can use it?
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"?
Also, the API works the other way around too – you can search by name to get the matching color: https://api.color.pizza/v1/docs/#api-Default-getColorNames. I did not add it to the website yet, because I don't have good UI ideas for it yet.
