Well, the colors on the chart are darker on my monitor than they are in real life.
The car looks purplish, but that's the way old film deteriorates.
I'd guess it was EE1 - CC1 that year wasn't a regular B-body color, but was for C-bodies.
Definitely not a lighter shade, like QQ1.
Here's my QQ1 car for comparison.
