The word "okker" is derived from the Dutch word "oker", which in turn comes from the Latin word "ochra". The Latin term "ochra" originally referred to the yellowish pigment obtained from the earth called "ocher". Over time, this word was adopted into various languages with slight variations in spelling and pronunciation. In English, it became "ocher", while in Dutch, it transformed into "oker". The term "okker" is therefore a variation of "oker" used specifically in certain regions or dialects.
