Why are Printed Circuit Boards Green?

Why are Printed Circuit Boards green?

Did you know that the vast majority of PCB’s are green? But, why are printed circuit boards green?

It is due to the solder mask, which protects the copper circuits printed on the fibre glass core to prevent short circuits, soldering errors, etc. The colour of the solder mask gives the board its appearance.
