[Aleksander]

The three-tone Bf-109 cammo is a misinterpretation of some damaged black-white colors. There were never three-tone Emils in VVKJ (Royal Yugoslav Air force)

Also, the profiles on
http://vv-colors.50webs.com
http://www.letletlet-warplanes.com
are all speculatory at best (most of them are imaginative, although the author has "researched" the topic)

All imported planes (SM.79, Ca.310, Hurricane...) retained their cammo, only VVKJ crosses were aplied.
