I'm sorry to say that I see a small problem with paint schemes of these A320's - namely that they aren't "SB-kosher"
- something that doesn't really matter in AU, but has some meaning in "real-life/never-built" sections: simply speaking the letters of logos and registration (incl. flag) are done with multiple shades, whereas basic principle in SB and FD is representing everything just by several (usually between 3 and 5) shades of any color.
Above is (oversized) sample of "what is" (with false colors added), below is "how it should be by the rules".
