Looking at tty-colors.el, a 16-bit values is being used for each of the three
colours
(R[0-65535] , G[0-65535] , B[0-65535]). Giving more possibilities than 24-bit
total values
(with 8-bit values for each of the three colours.
tty-color-define (w32console.el) passes each supported color, its index, and
its RGB values.
In tty-color-define, each one of the RGB components is a number between 0 and
65535 (16bit).
But unsure how many get passed to tty-color-define. There is nothing specified
in the .c files
about this.
