Thanks for the help with the green, I found BN green and sprayed on it looks the part....now for the yellow...could I trouble you for a suggestion of the appropriate yellow?
AHHHhhhhh....... okay, good news, bad news.
YES I can make a suggestion for the yellow. The bad news is that you should have applied the yellow first! In my experience, yellow covers pretty poorly. When I am doing AN models, I base coat, then spray the yellow. Generally only where it needs to be applied. Mask the yellow and then coat with AN green.
In your instance, I recommend that you spray the area that will be yellow, whatever your base colour is (I use a light grey), then the yellow, mask up and fix any green that needs fixing. Good luck!
Now colours... Same principle as before, look for something that is like ATSF Yellow. Have a look like you did for the BN green.
Cheers and good luck.
