Finally I discovered that Australia, Croatia, Brazil and Belgium wear all the same Nike font, which, for this reason, I think it's supposed to be the main new Nike font for 2006 and maybe it'll be worn even by club teams next year.
So I decided to give a specific space for the whole color numeration (1-22) to this new Nike font. Brasil and Australia fonts are particular, since they are colored in green 48 and green 49, while in the standard numeration only green 47 appears. To understand completely have a look at this color scheme I made:
ID COLOR
1 white (1)
2 black (2)
3 yellow (7)
4 yellow (10)
5 red (17)
6 red (16)
7 red (20)
8 red (21)
9 red (25)
10 purple (33)
11 green (42)
12 green (43)
13 green (47)
14 gray (56)
15 gray (52)
16 purple (32)
17 blue (58)
18 blue (59)
19 blue (60)
20 blue (61)
21 blue (62)
22 blue (64)
So finally I updated Australia and Brazil fonts and now I add Nike 2006 font in other colors. For example blue 61 is good for Croatia and yellow 10 is good for Belgium. Enjoy!
