Right this is my opinion. I think GNE need to debrand the Little Coaster buses and change them to 2019 livery. Here's why. 
Number 1. The branding on the side doesn't work or fit anymore for GNE, "Frequency bus service from Early to Late 7 days a week" 
This is more to the fact GNE don't run the service on a Sunday or Lates anymore. Most they run up to is 6pm with the exception being the 41 which runs till 8pm. 
Number 2, The branding doesn't make a whole lot of sense. For the 41 and 11 yes I can understand but the 42 42A and 19. Reason is the 42A runs all the way to Kingston Park and the 42 and 19 run into Northumberland. I could be wrong. 
This is just my opinion so I'd be happy if I missed something or I'm wrong about it lol
