the green was the evening news football paper. the pink was the evening chronicle's. when the two papers merged they kept the chronicle's pink colour for the football edition, probably just as a sop though.
You're right that the Green was the MEN and the Pink the Chron, and the key thing to know about the difference between the 2 papers was that overall the Chronicle was City-biased and the MEN was utd-biased. The Chron had been owned by City's early 20th Century Chairman Sir Edward Hulton (whose family went on to own and develop most of the Withy Grove printing works).
As City dominated the local media, utd struck a deal with the MEN to set up an office at their Bank St ground and, from then on the MEN became utd's paper.
The Chron was more tabloid in its approach and was very popular with working class Mancunians, but it hit financial problems in the early 60s. As the MEN's Manchester Guardian (today's Guardian) was helping the MEN's profits, the MEN was in a stronger position and took over the Chron. The owners of the Chron by this time had decided to focus their energy on London based newspapers, and they had moved away from their Manchester roots.
City's early 60s struggles probably played a part in the Chron's struggles as well.
However, the Chron's Pink was much more popular than the MEN's Green and so the decision was taken to drop the MEN's Green and concentrate on the renamed MEN and Chronicle Pink. Eventually, the 'and Chronicle' was dropped altogether. I researched the full story for "Manchester A Football History" and there's much more to it.
Meant to add that the Chron had a circulation of 250,000 in 1961 when the MEN took it over. They published both papers until 1963, but the Chron was being run down throughout those 2 years.
The Pink ceased publication in 2006.
