paint code EK2

my painter went to get the paint for my 1970 duster 340 today & was told the code EK2
( go mango ) other wise known as orange had metallic in the paint.
does any one out there have any experience with this ?
the car had been repainted white then red over its life but under the carpet & the windshield gaskit ect. where stock paint still existed no metallic is evident in the factory orange paint.
I really want the correct paint on the car .
Thanks for any help.
