German 2cm FLaK projectile colour

[earni74]

I cannot find this projectile colour in any of my books, in the past i was told it is a German Naval colour, the body is Green and "seems" to have a yellow band under the ogive and on top of the rotating band (2 bands), thanks

As far as I know green was also used for practice (I saw 2cm and 3.7cm üb painted green)

Can you find remnants of engraved arrow on body ?

The projectile is the "navy" 20x138/B SAP-T which would have been fitted with the IZ43 and tracer/heat relay. These originaly are painted blue with a band corresponding to tracer colour. The blue paint however is very prone to discolouring. Examples coming from peaty soil can show green, yellow and even reddish-brown hues.
Edit:
As Minenaz says, Green was used for practice, an arrow stamped into the body would be a surefire ID.
However, this projo is of the short based SAP-T type without crimping groove for which I have not been able to ID an "üb" yet (neiter in documents, nor in physical evidence).
