Green, purple, yellow — what the timing screen colours mean and how to spot who's really fastest.
You watch qualifying and see Hamilton flash purple in the first sector, then Verstappen goes green in sector two. But who's actually faster right now?
Each F1 lap is split into three sectors — roughly equal sections of track that help you track performance through different parts of the circuit. Sector 1 usually includes the start/finish straight and first few corners, Sector 2 covers the middle section, and Sector 3 brings you back to the line.
The timing screen shows these sectors in different colours, but it's not just decoration — it's a live comparison system that reveals who has the ultimate pace and where they're finding it.
Purple means that driver just set the fastest sector time of the entire session — nobody has gone quicker through that section today. It's the absolute benchmark.
Green means personal best — faster than that same driver has managed in that sector during this session, but not necessarily the quickest overall.
Yellow means they're slower than their own best, while white or no colour means it's roughly the same as before.
This creates a fascinating puzzle during qualifying. A driver might go purple in sector 1, green in sector 2, then yellow in sector 3 — meaning they had the ultimate pace early but lost time at the end.
Meanwhile, their rival might show green, green, purple — consistently improving and nailing the final sector. The question becomes: can the first driver find those final tenths, or will the second driver put together the perfect lap?
Now when you watch qualifying, you'll spot the real story unfolding. Look for drivers flashing purple in different sectors — that shows you where the ultimate pace is hiding around the track.
If someone goes purple-purple-yellow, they've left time on the table and will definitely try again. But purple-purple-purple? That's a lap that's going to be very hard to beat.
