My understanding is that it is a horse-racing phrase. Some unprincipled
racers would dye a horse to disguise him and get better odds. Obviously
this only works to make a horse darker. A "dark horse" is an unknown
quantity -- the phrase is usually only applied to horses that show well
without the normal track record preceding that success.
