From the "I-want-colors" camp, I am hearing that by Yellow it is not
yellow per-se but some variation of yellow.  

The definition of Yellow is so broad that it will go to the extent of
embracing face with a yellow background or even a reverse video of it.
Visually speaking, you will see Yellow - a light one or a bright one, in
either foreground or background etc.  Where yellow occurs is not
guaranteed, but you will get yellow.
