While I agree the LSD is somewhat meaningless, I personally find it fun to test my color matching/mixing. Binary search circumvents that (at least for the most significant digit); though I agree it really only applies for the first and maybe second guess.
For instance, my initial guess was off by (+1,-1,-1,+3,-1-2) and my first impulse was to look at the target and see that I had too much red and not enough green.
