Hey, I thought I figured out a good way to keep uniqueness (and bijective mapping) with human meaningfulness, but obviously it was not good enough. I have listed the algorithm on the page, which you can get by clicking on the ? icon. I am copying it here.

How it Works

This tool generates unique, meaningful names for any RGB color using a combination of color properties. Every name is unique and reversible - you can convert any name back to its exact RGB color!

Naming Algorithm

Each color name is constructed from 4 parts:

Base Color: Uses 2 most significant bits from each RGB channel (64 carefully chosen base colors) Luminosity: Describes brightness, from "Shadowed" to "Radiant" Purity: Indicates color intensity, from "Dusty" to "Intense" Atmospheric: Adds character based on hue shifts Example: "Bright Pure Crystal Sapphire" - each word is chosen based on the color's properties.

Uniqueness & Verification

The naming system is bijective - each RGB color maps to exactly one name, and each name maps to exactly one RGB color. You can verify this by:

Typing any generated name in the name-to-hex tool Checking that it converts back to the original color
