get_driver_color_mapping not working for 2025

[noehurtado]

Hi, it seems that get_driver_color_mapping is not working for 2025, if I run the exact same code but for 2024 (as seen in the picure) it works, but while trying to get the colors for 2025, it's not working.

Please ensure that you have updated to the latest version of FastF1 and let me know if that fixes the problem. There were some issues that needed to be fixed around driver colors at the beginning of the season.

Hi, yes, I thought that might be the issue, so I checked it beforehand. I'm currently running FastF1 3.5.3

This code

import fastf1
import fastf1.plotting

session = fastf1.get_session(2025, 1, "FP1")
session.load(telemetry=False)

c = fastf1.plotting.get_driver_color_mapping(session)

print(c)

for me returns

{'VER': '#0600ef', 'LAW': '#0600ef', 'GAS': '#ff87bc', 'DOO': '#ff87bc', 'ANT': '#27f4d2', 'RUS': '#27f4d2', 'ALO': '#00665f', 'STR': '#00665f', 'LEC': '#e80020', 'HAM': '#e80020', 'TSU': '#fcd700', 'HAD': '#fcd700', 'ALB': '#00a0dd', 'SAI': '#00a0dd', 'HUL': '#00e700', 'BOR': '#00e700', 'OCO': '#b6babd', 'BEA': '#b6babd', 'NOR': '#ff8000', 'PIA': '#ff8000'}

which looks correct.

You are sure that you are using the latest version and didn't accidentally update a different environment? If 2024 is working correctly, this bascially excludes networking/connection issues to the F1 livetiming API.

You are correct, not sure why although on the terminal was showing me the latest version, my notebook was running the previous one. Thank you so much!
