The RGB/backlight color of my keyboard gives me a completely different color than the one I selected through the Driver.

It’s because the bottom housing of the switch and the keycaps are a different color and the plate may be polycarbonate, therefore, causing the color of the light to be distorted. You could check it without the keycaps it should be okay.

This issue could happen on Blue on White 5075B Plus – Akko V3 Cream Yellow or any other RGB keyboards.
