To all that are interested. I have just been informed by Porsche Germany, that the two colors are not compatible. Probably OK if just in the stitching, but not OK if used on the seat covers and door panels. The colors are not complementary.
“Papaya” for interior stitching and seat base & door highlights does not exist as an option. Would choosing “Orange” interior elements be compatible with the “Papaya metallic” exterior, or would it clash?
