24 alternatives to I built a tool to describe ~4.3B colors
A simple tool I made over the week to explore and learn about different colors. You can select any color with any opacity #000000-FFFFFFFF (~4.3 billion colors/variants), and you can view a dedicated page detailing the color's closest name, conversions to Hex, RGB, CMYK, etc., shades, tints, tones, harmonies, opacities, and WCAG contrast compliance.
Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. I built a tool to describe ~4.3B colors launched in 2022; newer entries below may have overtaken it.

I had this idea kicking around in my head for quite a while. Took an evening to make this, and a short morning to polish it a bit. So here it is!

Hi HN, I’m Emil, the maker behind Palette. I’ve been tinkering with AI and colorization for about five years. This is my latest colorization model. It’s a text-based AI colorizer, so you can edit the colorizations with natural language. To make it easier to use, I also automatically create captions and generate filters. Let me know what you think. You can see some of my results on my reddit page: https://www.reddit.com/user/emilwallner/?sort=top

I crawled lots of websites and extracted their color palettes (primary, secondary, etc) to build a searchable collection of website colors! It was a fun side-project and I learned a lot about color theory. Let me know what you think and what features you would like to see :) If you have any questions about the tech behind it, feel free to ask in the comments. Feedback is also greatly appreciated.

This is a personal project I've been working on for a long time now. I stumbled upon the color quantization problem while doing something related for work. I then found an interesting paper for which I could find no implementations online, and the thing went from "let's implement this paper" to getting pretty obsessed with the whole thing. It's at an early, eaaaarly stage. There's a lot of work to be done, and it's a memory hog, but generally speaking works quite well, and the output is for the most part very high quality, so I'm happy to share it as beta.

I built this API to return the closest named color for any hex value—using curated lists like my own [1], XKCD [2], and others. I made it from scratch without Express or any frameworks because: - I’m a frontend/interaction dev and wanted to learn how to build an API from the ground up. - Existing APIs didn’t guarantee unique names per color—mine does. - It also supports WebSocket updates, gzip responses, and multiple name sets. I’ve been collecting color names for over 10 years [1]. With ~30,000 entries, bundling them into every color-related project became excessive. This API keeps…
