A uniform corporate colour cannot be evidenced for Soennecken in this period; the available historical documents are often only available in black and white. Soennecken used various colours for different products, apparently without a recognisable system, and also printed the company inscription in different colours on the packaging. A systematic colour code for the nib boxes or distribution packagings is therefore not handed down. Since Soennecken today belongs to the brand group Branion and no own company museum exists, detailed information is difficult to obtain.
