Colors can be hard to determine for any given year.
The color charts are fairly accurate. But the manufacturers played pretty loose with color selection. Some colors not represented on the charts were carried over, for a while, into the next year. There were a lot of "Spring Specials" or regional color combos available that would not show in the charts. There were also some cases when a new color would be added mid-year, then carried into the following year. As such, I'm comfortable knowing the color of any particular model falls within a two to three year set of offerings, the production year, the year before and the year after.
