haha cant say ive ever noticed lol

That's an interesting question....let me see if I can dig something up...okay...got it...

During the 1800s, the best graphite in the world came from China. American pencil makers wanted a special way to tell people that their pencils contained Chinese graphite

In China, the color yellow is associated with royalty and respect. American pencil manufacturers began painting their pencils bright yellow to communicate this "regal" feeling and association with China.

The rest, as they say, is history. Today, 75% of the pencils sold in the United States are painted yellow!
