The Norgeskatalogen only mentions that the first version from 1955 is "Mørk grønnblå" (dark greenblue) whereas the one from 1962 is just greenblue. There is a footnote though, that says "the 1962 stamps were printed with new cylinders. These stamps have unclear print and the background colour is lighter."
