I am using ili9486 with ESP32 with TFT_eSPI library. it is in 8 bit parallel mode. Red, Green and Blue are correct if i draw test or filled rectangles. But Green and Blue are swapped if i draw bitmap using PushImage. i converted image to c file by Rinky-Dink Electronics
Secondly i noted that colours are dim if drawn by bitmap. while they are bright if i draw something myself.
