Frequently asked questions

What is the paint code for Porsche Oslo Blue?

Oslo Blue has carried Porsche paint codes 6203 (historic 356-era code); Z77 (modern Paint to Sample code (vendor listing)). Porsche reuses names across eras with different codes, so match the code on the car's option sticker or build sheet rather than the name alone.

Which Porsche models and years came in Oslo Blue?

Our sources list Oslo Blue on the 911 Carrera RS 2.7 (1973, special (extra-cost) color) and 911 (992) (2021–2022, paint to sample). If you see it on a model or year not listed, it may be a Paint to Sample order or a respray — the build sheet for the VIN shows which.

Is Oslo Blue a Paint to Sample color?

Yes, on some cars: our sources list Oslo Blue as Paint to Sample on the 911 (992). Paint to Sample is Porsche's extra-cost program for pre-approved colors outside the standard palette.

How can I tell if a Porsche is factory Oslo Blue?

Read the paint code on the option sticker (in the maintenance booklet and, on most models, in the front luggage compartment) or on a build sheet for the VIN, and compare it with 6203 and Z77. A matching color name alone does not rule out a respray or wrap.
