I was looking for a list of RGB hexcodes online in json format that you can simply load into a program but I couldn’t find one. So I generated one. I have included all color defs I could find, CSS4, X11 and XKCD.

The json file is here. It’s really easy to use in Python, you just load the requests module, call requests.get() on the url (find it by following the link below). That will give you the json content as a string that you can decode using Python’s json.loads() method.

import requests
import json

url = "https://codeberg.org/mok0/gist/raw/branch/main/color-hexcodes.json"
response = requests.get(url)
hexcolors = json.loads(response.text)

Here’s the list of 1513 colors:
