Picture a pencil and it is probably yellow with a pink eraser. That colour is a 130-year-old marketing decision.
The Koh-i-Noor pencil
In the late 1800s, the Austro-Hungarian company L. & C. Hardtmuth launched a premium pencil named Koh-i-Noor — after the famous Indian diamond. Introduced around 1890, it was painted a striking yellow and marketed as the finest pencil available.
The China connection
The usual explanation for yellow is that the best graphite of the era was said to come from China, where yellow was associated with royalty and the emperor — so yellow signalled quality. Historians treat this as a plausible story rather than a documented fact, but the colour certainly became linked with premium pencils.
Everyone copied it
Other makers painted their pencils yellow so they looked as good as Koh-i-Noor. In the United States, yellow became so standard that a pencil of any other colour looked “cheap” for decades.
In India
Indian pencils took a different path: the red-and-black striped design of popular brands became just as iconic in Indian schools — a reminder that what looks “normal” is often one company’s design choice.
