Colour of Fallschirmjager parachutes

[Boomerang]

I am seeking information about the use by the Fallschirmjager of colour coded parachutes to designate supply drop containers delivering different types of materiel. My current understanding is that coloured parachutes were used this way in the Crete operation.

Any information to confirm this, and about what colours were used would be very helpful for a modelling project.

Thank you
