Why do Scantrons need #2 pencils?

(You can read more about how old scantron machines worked if you’re a big nerd like me.).
Why are pencils yellow?
The one thing that is agreed upon is that in the late 1800s, when people started painting pencils, the finest graphite in the world was coming from China. And so yellow became a color that was associated with a pencil because it was a way of indicating that your pencil was made with superior Chinese graphite.
What are number 2 pencils?
An American #2 pencil (roughly) corresponds to an HB pencil on the rest of the world’s scale. The lead is not too dark and not too light, and it’s not too hard or too soft.

What does 2B stand for on a pencil?
Soft leadsSoft leads are graded using the letter ‘B’ to designate how ‘black’ the mark they make is. Numbers are then used to indicate the degree of softness – the higher the number the softer the lead and the blacker the mark. For example, a 2B lead is softer than a B lead and will produce a blacker mark.

Pencils ranging from 2B to 9B are softer still and are used for sketching; 2H to 9H are harder than average. A common American #2 pencil is equivalent to HB.
