Because there's 16 million possible colors to name. Even if you count the fact that some of them have the same color, you still have to build through a database that big and search through it.

ChatGPT doesn't know 16M color names, it knows 480, well that's all I could get out of it by asking e.g. what color names are between eggshell and pearl.
The code above gets the closest color name to any of the 16M hex codes. There's 550 colors in the list.

Tearing through your API allowance 10 times a second, is horrific.

This review doesn't even mention color names, lol.

When I saw that I was like, why do I need to to connect chatGPT for a color grabber?? 😂
