In fact, this screen fits to Raspberry Pi 3B/2B/B+; but you must use the bread cables to connect them, because it's male pins on the this screen, and it's male pins on the pi 3B also;

Yeah, I have been fighting with it for the last day and Claude hasn't been able to figure out why it is blue-tinted.  Tried adjusting the tint in vlc, but it has no effect as the display itself is blue tinted.

I have the old 2.8" iUniker/Geekworm DPI display and am using Pi OS Trixie.
I have gotten it to work as a display by running the following routine which puts the configuration over in the correct location.

but... the colors have a decidedly blue hue to them that didn't exist back in Bullseye (reds are shifted more toward purple, greens are shifted more towards blue, blacks are more navy than black).  What tweaks can I make to make to bring the color back to the correct place?
