Polish helmet paint variant

[Trwade]

Hello! I recently acquired a handful of these Polish Wz50's with these paint schemes, My guess is they are some navy/airforce or training paint variant but I'd love to get a confirmation if anyone knows what the paint schemes meant they were used for.

The blue one is the standard navy issue. Green one is also navy but why it was painted over in green I don't know
