      Exactly.

      They could very easily just keep the color for color seeing people, and then add a simple pattern in the background.

      Like maybe diagonal lines on one, wavy horizontal lines in another, small dots in another, etc.

      Just pretend you are taking a black and white picture or making a black and white copy on an old copy machine. Can you still interpret the data afterwards? If yes, then you did it right.
