I use a Python script to extract the dominant color from the album art of the currently playing track and update the color on an ESP32 display accordingly. I’ve prepared a custom component in case anyone wants to try it out:
A small, standalone custom component for Home Assistant that monitors
the album art of a selected `media_player` and exposes its dominant color
as a standard `light.*` entity (RGB)—without needing a `python_script`,
custom automation for each device, or modifications to the YAML
configuration of any target device.
I think you forgot the link?
