Color chart shows 4 different blues, 2 each of gloss and low-gloss. That said, here's what all of mine ('68-'70 B-bodies) were:
Suede dash, column, ashtray, windshield header mldg.
Gloss door & quarter metal and headliner side mldgs.
Molded color for A-pillar mldgs, kick panels, defroster vents, seat hinge covers, seat belt buckle retainers.
Package trays were same as darker seat material, and I believe consoles were as well, if not same shade (different finish) as dash (none of mine were console cars).
The molded plastic parts faded with sun exposure.
On blue interiors, '68 used a light blue on doors/quarter trim, '69s were darker.
The plastic bits in my green-interior '68, '69 & '70 cars were all the same shade of green.
When we'd find these cars in the junkyards & strip their parts, the colors were consistent regardless of model and body.
