cfcolor 1.0.0

CF Colour Protocol -- deterministic colour identity

cfcolor

Python reference implementation of the CF Colour Protocol.

Every 8-bit sRGB colour has exactly one CF-ID — a stable, deterministic, verifiable identity computed from first principles.

Install

pip install cfcolor

Usage

from cfcolor import from_hex, from_rgb

from_hex("#7B3F00")     # "CF-7B3F00-EA262463"
from_hex("#000000")     # "CF-000000-86165F20"
from_rgb(255, 0, 0)     # "CF-FF0000-37AB74A7"

Command line:

cfid "#7B3F00"
cfid "#7B3F00" --json
echo "#cc0000" | cfid
