The term "blackboard" originates from the traditional color of the writing surface, which is typically black or dark gray. This color allowed for high contrast with white or colored chalk, making it easier to read from a distance. While modern boards can be green or other colors, the name "blackboard" has persisted due to historical conventions. The green board, often referred to as "greenboard," is just a variation that became popular later.
Blackboards are typically dark-colored for better visibility of white or light-colored chalk markings. The dark surface helps the writing stand out and be easily readable. Additionally, blackboards were originally made from slate material, which naturally has a dark color.
Blackboards are not scratched by chalk because chalk is softer than the material from which the blackboard is constructed. Sand scratches blackboards because it is harder than the material from which a blackboard is made.
