Yes seems like this could of been better drawn but both stops appear to be in red with none in the green, therefore all stopping points in red zone

The 4 is:

• Houghton-le-Spring Church to Penshaw Bank Top - red
  
• Penshaw Bank Top to Heworth - purple
  

The 78 goes into the green at the first stop after it turns right to go towards Lumley, rather than after the mini roundabout as seems to be indicated on the app's map.
