Spectraflame olive (1968) and lime
 
Difference between 1968-olive Spectraflame and lime Spectraflame.  This picture shows the difference between 1968-olive and lime.  The Custom Volkswagen on the left is painted in the first shade of olive.  This olive has a golden hue, and is unmistakeable.  Cars from 1968 and 1969 were painted in both shades of olive, what I call 1968-olive (olive gold) and 1970-olive (olive green).  1968-Olive Spectraflame paint was phased out by 1970.
