Using a library to manage 2 bytes (16 bits) colors might be considered

Here is a schema for such colors representation (aka RGB565)

1        |1          |        0
5 4 3 2 1|0 9 8 7 6 5|4 3 2 1 0 
---------|-----------|---------
R R R R R|G G G G G G|B B B B B
  • 5 bits for red channel - 32 values

  • 6 bis for green channel - 64 values (green gets an extra bit because it's the main element of luminance)

  • 5 bits for blue channel - 32 values

Name R G B value
BLACK 0 0 0 0
WHITE 31 63 31 65535
RED 31 0 0 63488
GREEN 0 63 0 2016
BLUE 0 0 31 31
GRAY 16 33 16 33840
BROWN 23 34 0 48192
YELLOW 31 63 0 65504
