Pai was shocked that Indian students could answer questions on Greek and Roman mythology, but were ignorant of their own history, mythology and folklore. The original printings of Amar Chitra were not in full colour because of budgetary constraints, the panels were printed using yellow, blue and green. Subsequent issues, however, changed to full colour. All Amar Chitra Katha books stuck to a monthly (later fortnightly) 30-page format, with emphasis on lucid, entertaining storylines. In addition to the 'singles' format the stories are also available as hardcover 3-in-1 and 5-in-1 bundles. There are special editions of the Epics like the Mahabharata which is available in a 3 volume 1300 pages set.
