The Spies Hecker Color Index documentation is a big help in finding the exact colour.
Colour chips give you a complete overview of all OEM colours and their variants. They are in alphabetic order by car manufacturer (OEM) and colour code and are updated yearly. The flexible chips are painted with original Spies Hecker paint to facilitate finding the correct colour on the object to be repaired. The corresponding colour code is on the back of the chip.
In addition the Hi-TEC and add-on parts documentation (Color Index Specials) have barcodes on the back of the chip for easy scanning.
