Yes - but if you can set up your own palette, you can still arrange
that the even numbered values for G have the same brightnesses as
the equivelent R's and B's.  Admittedly, this will mean that
"White" will be 1/31 == ~3% dimmer than you might expect...but
that's a small price to pay for nice greys.
