The arrival of yellow on the Williams cars coincided with the reign of Keke Rosberg, the reigning champion who, alongside Frenchman Jacques Laffite, became the first to pilot a Williams Racing livery with the bright yellow splash. Rosberg's 1983 Monaco Grand Prix victory marked the first of 55 yellow-equipped wins for the team, a testament to the color's association with success.
The yellow accents, initially located just under the roll hoop, soon expanded to further parts of the car, including the nose cone. This eye-catching design element not only stood out on the track but also represented a partnership with a chemical company, further solidifying the team's commercial relationships.
The following two seasons, 1986 and 1987, saw the team's fortunes take a turn for the better, as the yellow-topped FW11 and FW11B cars propelled Williams Racing to championship-winning glory. With Brazilian Nelson Piquet joining Mansell in the garage, the duo won 18 of the 32 grands prix over the two seasons, showcasing the team's dominance and cementing the yellow, blue, and white livery as an F1 icon.
The team's success during this period was nothing short of remarkable, with the World Constructors' Championship being won by a margin of 45 points in 1986 and an incredible 61 points in 1987. Piquet's title triumph in 1987 further solidified the yellow livery's place in Formula 1 history, as the team's prowess on the track was matched by the striking visual identity that had become a symbol of their achievements.
The following year, 1990, saw the Belgian driver and Italian Riccardo Patrese help Williams Racing become the vice-champion team, securing two further wins in the yellow-adorned cars. The arrival of a new partner in 1991 did not diminish the prominence of the yellow hue, as it continued to grace the team's new FW14 car.
The return of Nigel Mansell to the Williams Racing fold in 1991 marked a significant moment, as the Mansell-Patrese partnership went on to win seven races in the team's fight to reclaim the top spot in the standings. Although Mansell and Williams Racing had to settle for second-place championship positions that year, 1992 proved to be a triumphant one, with the famous FW14B car.
The FW14B, with its prominent yellow livery, was a true force to be reckoned with, as Mansell secured nine wins, including five successive first-place finishes. The team's dominance was further highlighted by the six 1-2 finishes, culminating in the Constructors' and Drivers' titles coming to Grove.
The yellow livery remained for one final year in 1993, and it continued to enjoy more successful times, as Alain Prost secured his fourth and final title alongside Damon Hill. Prost's seven wins and Hill's trio of victories helped Williams Racing to one of its most dominant seasons, with the team finishing the year as champions with double the points tally of their nearest challengers.
