Thanks Amigo! By the way, one thing I am concerned about here. I think the blue will differ from the roundels provided. May need someone to come up with masks. On the other hand could just be due to a thinner application 
I hesitate a bit about posting this but I do want to help a bit and don't want to "toss a spanner in the works" as it were. However...in correspondence with Rowan Broadbent, he indicated at one point that Citadel Paints for figures had two colours that matched the red and blue that he uses for his RFC/RAF national markings. Now, don't blame us for the names but the blue colour is "Kantor Blue" and the red is "Evil Sunz Scarlet"...really!

Here's a photo of the rudder of my Albatros DV "Captured" showing these colours:
These paints are very thick but they thin nicely with Tamiya thinners and probably with IPA as well. Hope this might help a bit!
