Since the Mirage books and original run had black and white interiors, they all had the same red colored bandanas. It was the Archie animated series, along with the cartoon that introduced the different colored masks that we all have become accustomed to. The animated series also introduced Bebop, Rocksteady, and Krang.
Growing up in the 80’s, I wasn’t even aware of the red masks until I got into the Mirage books and studied their history. My first comic book was TMNT Adventures 5, with “Man Ray”, or “Ray Fillet” as we know him today! Here is a sketch I got Andy on the boards by Michael Dooney back in 13’. It’s currently hanging on my office wall.
