    I don't know your [particular hardware but, speaking as a digital photographer, my understanding is that setting RGB to the same value will produce a neutral colour (assuming calibrated display hardware), somewhere between black and white inclusive.

    Whether the colour is grey or not depends on the overall intensity. By convention, setting R=G=B=<minimum value> should typically result in black, R=G=B=<maximum value> should typically result in white.
