F1 sector colours explained In F1, the three main sector colours used are purple, green, and yellow- and are used to determine just how fast a driver has gone through each sector on a lap. A purple sector in F1 signifies that the driver has just set the fastest time through that segment of the lap.

The sectors in Formula 1 racing help drivers accurately gauge how fast or slow their car is going on the course. These sectors are labeled purple, green, and yellow which tells racers how fast they are going and where their car is dragging.

Timing screens use 3 colors to display the speed of a sector’s time. These are purple, green and yellow. The colors appear on a screen next to the driver’s name and lap time.
