I have a 1970 Cutlass Supreme with a Blue Interior. The question is what Shade. Bucket seats come in Medium blue from Opgi and light Metallic Blue from Legendary. Then there is all the various colors for your Hard Trim, soft trim, carpet and Headliner. Its all a little confusing

 

If in doubt, see if the vendors (the actual manufacturer, not the reseller) will send you samples of the vinyl for all the blues. Better safe than sorry, given the cost of these items.

 

Problem is a lot of the old plastic and so forth is discolored... badly.

 

The Light Metallic Blue from Legendary is correct.

 

The kickpanels are a darker blue than the seat plastics. As is the top of the dash and rear window metal piece. Find a blue that matches the seat material and use that for a lot of the soft trim if you want. Are you missing all those pieces?

 

The Light Metallic Blue is my favorite 70 interior color but it is hard and expensive to restore. There are three shades of blue on this interior. As mentioned above, Legendary has the perfect match and highest quality. The correct paint to match the Legendary interior can be bought from Kolor Korrect, their phone # is 732 846 1044. Not cheep. I never found a perfect match for the dash pad but got close enough.

This is Legendary and Kolor Korrect in these pictures.
