ST7735 display and picture and pictures

well i build a MAC16 palette in photoshop as your script does (the online tool)
now i can export the image "as is".

Now on my screen, the color does not match.
what is suppose to be a gray #bbb is purple and the gray #444 is green...
no matter i change the palette reference by reorganize (in photoshop) the place of each color as in your coded palette...

oh and i use your palette as the ref palette.
what's wrong?
