I recall someone telling me the reason they were told that Cavallinos are black vs chrome on the back of GTOs, but I don't remember the story (the person had just returned from a factory tour- they were purchasing a then-new 599 GTO). Was it that Enzo Ferrari was ticked off about the homologation requirements for the 288GTO and the tradition stayed for the 599 GTO? Or to use the black for race cars to honor the deceased? I can't remember the story... From Wikipedia: On 17 June 1923, Enzo Ferrari won a race at the Savio track in Ravenna where he met the Countess Paolina, mother of Count Francesco Baracca, an ace of the Italian air force and national hero of World War I, who used to paint a horse on the side of his planes. The Countess asked Enzo to use this horse on his cars, suggesting that it would bring him good luck. The original "prancing horse" on Baracca's airplane was painted in red on a white cloud-like shape, but Ferrari chose to have the horse in black (as it had been painted as a sign of grief on Baracca's squadron planes after the pilot was killed in action) and he added a canary yellow background as this is the color of the city of Modena, his birthplace. The Ferrari horse was, from the very beginning, markedly different from the Baracca horse in most details, the most noticeable being the tail that in the original Baracca version was pointing downward.
