Usually you use "18% gray" meaning a card that reflects 18% of the light
in the visible spectrum and equal amounts of red, green and blue.
It might actually be nice if the whitebalance module would support
exposure adjustment as well, to make a selected area a specific
brightness, or what do others think?
by the way: what is the color of the remaining 1%
That "33-33-33%" is your invention, so nobody but you can know what
"remaining 1%" you are talking about. If you were talking about the
reflected % of the individual color channels then there is no "remaining
1%", but the "remaining" (absorbed) amounts of light are 67%, 67% and
67%, respectively.
