According to Mosca, the blue and green stripes symbolised movement and aggression, while the overall yellow colour symbolised youth; the three colors were also identifiable with the flag of Brazil. The helmet never had significant changes, apart from sponsorship. One such change was that Senna occasionally altered the stripe from blue to black. The tone of yellow changed a number of times, while usually a rich sunburst yellow, in 1985 and 1986 in some races, he used a fluorescent neon yellow colour. In 1994, the helmet was a lighter, paler yellow to complement the blue and white of the Williams car.
