Select a video track, go to Effects and click on Color Correction> Three-Way Color Corrector. This video is on the underground so features a yellow colour cast.
Click on the Dropper under the Midtones dial. Now click on a mid-tone on the video itself. Repeat the process for the Highlights, looking for a bright yellow.
Repeat for the Shadows then tweak the Balance Magnitude (circle control) and Balance Gain (oblong control) to take out the remaining colour cast on the train.
