  Green sparks concern...

  When I did my first Physics class, I was horrified to learn that they
  had lied to me... What I thought of as Red, Yellow and Blue were
  actually Magenta (a "type" of Red), Yellow, and Cyan (a "type" of
  blue)*

  [Anita Hillin]  What you learned in Physics was primary LIGHT color, which
is likely a better reference to the sparks than the first primary color
wheel you learned, which is PIGMENT color.  Primary light colors are red,
green, and blue, and the secondaries are amber, cyan and magenta.  All three
together make white, by the way.  Red and Green do, in fact, make yellow or
gold in light, so the combination of the two light sparks could create a
gold color.  By the way, I learned that in Theatre Stagecraft.  ;-)
