Yep, one CW-21 was captured and flown in Japanese markings! Photos: see Google.
They were published many years ago in Air Enthousiast I believe.
Some Dutch Falcons were also captured. Even in 1946 one of these was photographed in Kalang, Singapore but I have never seen these.
Colour scheme of CW22 was same as for CW-21 Interceptor: a mix of light/medium green and dark green, often described as 'new leaf and old leaf colour'.
