GINGER: How Red is Red?

[Tracy]

Well, now you've got my curiousity piqued as well.  I associate the 
word "ginger" with a brownish color (like the powdered kind, or 
gingerbread); or white if we're talking about the fresh kind.  I 
found this example of red ginger:

I noticed that "artificial color" is listed in the ingredients, 
though.  

Maybe there is a variety of the plant which has red blossoms.  I'm 
not even sure what the above-ground part of a ginger plant looks 
like!  Where is Professor Sprout when we need her?!
