It's a common misperception that red cloring produces
a red tinge in this context. It doesn't. As I said
before, it becomes a color that isn't close to
anything the body can produce whereas blue dye can and
often does make the substance found greenish yellow.
Red coloring has been used by nurses with enteral
feeds for many years and for the above reason.
