Aviation Academy Graduate Badges, what is the significance of the colour ?

[plmurphy]

I have a number of graduate badges in my collection all to what I believe is the State Aviation Academy (feel free to correct me if I have the name incorrect). So far I have the same badge in navy, red, and yellow. I am also aware of a pale blue version. Does anybody know which disciplines are represented by the different colours ? Pale blue, for example, normally represents pedagogical studies but that is hardly the case for an aviation academy !

The badges are attached for those who are interested. First up, the navy version.

Next up, the red version, more a sort of dark orange.

Finally the yellow version.

Any help in getting more information on these would be appreciated.

Better to say "Civil Aviation".

Many thanks, anybody know the significance of the different colours ? ie. which branch was represented by which colour since I presume this is what they indicate.
