After an update I noticed discover was this weird yellow color, I opened settings and noticed it too was yellow, thinking it was some bug, I restarted PC, now everything is yellow. I tried inverting colors but that is something completely different. I’m not even sure what was updated to cause this.
I’m running mint 21.3 with plasma 5.27.11
Your colors are inverted.
The accessibility icon never follows accent color, and firewall is always red not blue. Something is swapping your colors around.
Maybe color correction for the color blind?
Blue -> Yellow
Red -> Blue
Your message actually helped me find a post of mint forums who had the same problem the day before it happened to me, was a graphics driver from oibaf ppa.
