Built a Raspberry Pi Zero 2W + 64x64 RGB LED matrix Spotify album art display — colors are way off, looking for advice
Hi everyone,
I'm a music lover (not a developer) trying to build a little DIY display that shows the album art of whatever I'm playing on Spotify. The setup is a Raspberry Pi Zero 2W with an Adafruit RGB Matrix Bonnet and a 64x64 P3 RGB LED panel (FM6124D chip, E-line soldered).
The display works — it shows the album art and updates correctly — but the colors are completely wrong. Red LEDs are about 10x brighter than green and blue, so almost everything looks red. I've been applying software color correction (scaling down red, boosting blue) but I can never get the balance right across different album covers.
Some things I've already tried:
- Various
led_rgb_sequencesettings panel_typeFM6126A (makes things worse)- Software color correction with different multipliers
- Custom Pillow shim compilation to fix pixel reading
My current power supply is 5V/4A — I've read this might actually be the root cause, with insufficient current causing green and blue to drop out under load.
Questions:
- Could a stronger PSU (5V/6A or higher) actually fix the color imbalance?
- Are there known color calibration settings for this type of panel?
- Is there a better approach entirely that I'm missing?
Any help appreciated — I just want to see my album covers in the right colors!
