Color calculator for Arduino Display
I built this tool for ST7735 display but it should work fine with any other 16-bit display.
To use online color converter for Arduino boards type the 24 bit RGB HEX representation of the color into source input RGB565:
24 and 16 bit colors might look different.
Interesting fact that a human eye diffirentiates more shades of green and this is why TFT displays have 6 bits for green color.
