Some displays are BGR order rather than RGB or the other way around. For now, you can either try changing the MADCTL value at https://github.com/adafruit/Adafruit_CircuitPython_RGB_Display/blob/main/adafruit_rgb_display/st7789.py#L146 from 0xC0 to 0xC8 or the one at https://github.com/adafruit/Adafruit_CircuitPython_RGB_Display/blob/main/adafruit_rgb_display/st7789.py#L101 from 0x08 to 0x00. Honestly though, it's common enough that we should add a parameter to do this automatically. Also, we should probably change it to be done in one operation rather than 2.

Hi Mel,
I'm using - 1.8" TFT Display Breakout and Shield with an EYESPI breakout

To fix this issue on st7735 in class ST7735R(ST7735):

Change
(_MADCTL, b"\xc8"),
to
(_MADCTL, b"\xc0"),

works for me
