For Dutch Catalinas was introduced the same colour scheme as for Do-24, but colours may be difficult, due to Catalinas were painted in factories with US paints. There are signs of overpainted insignia on fuselage - orange triangle is smaller than primary was, and orange rudder is overpainted to nothing. Nobody knows, were tactical numbers (Y-38 to Y-73) painted in proper places i.e. under the tail.
