AS355NP Fuse cover color

[Harrynz]

I have just had look through the window of a new AS355NP. I fly an AS355F1 so I was keen to see the differences and I am quite impressed.
I noted that the fuse covers in the upper fuse panel are Black, Yellow and Green. Anyone know what the colors are meant to indicate?
The pilot was not around to ask and I have tried an internet search but found no info so far.

Yellow - Radio, Radio Nav and AP-CPL
Black - Electrical and mechanical systems monitoring or unused positions
Green - Electrical systems monitoring

Still no circuit breakers?

It's being considered on the assembly line.

Thanks Curtis.
I was expecting something more complex or confusing from Airbus Helicopters.
