Back in the late 90s to Early 00s Lamborghini used yellow in a lot of cars, like the Diablo, Gallardo and murcielago. When I was kid I thought this was so cool. It really gave Lamborghini that Ferrari vibe. If Ferrari got red, Lamborghini got yellow, that’s was the name of the game for me. It was such a cool branding move. I don’t understand why they stopped with it.
The first Ferraris and Lamborghinis were often Giallo Modena as a tribute to Modena. I’m guessing that with more recent cars that connection probably became less important and marketing started playing a bigger role.
