Has anyone encountered the issue of color deviation after loading an image onto a device? How can it be resolved?

How-to
1

lvgl version ： 8.3

lvgl configuration:
#define LV_COLOR_DEPTH 16
#define LV_COLOR_16_SWAP 0

The image is supposed to have a blue background, but after being loaded onto the device, it appears orange, as shown in the background color of the second image. I checked the color channel order using a tool and it is in RGB sequence.
1_1_1_on

Are you sure this is not HW problem? It looks like the red and blue colors are reversed?

Ah！ finally， i found that the st7789 has a command to set the color channel

in one projects of mine. i had to swap the colors using

lv_draw_sw_rgb565_swap(color_p, (area->x2 - area->x1 + 1) * (area->y2 - area->y1 + 1));
