For those unfamiliar with PCB printed circuit boards and how they are made, there is a common misconception that all PCB boards are green. However, it is not. PCB printed circuit boards come in many colors, and these different colors exist for a reason. Let's learn more about printed circuit board colors, variations, and what they mean.

While green is still the most prominent color for a PCB printed circuit board, other colors used include blue, red, yellow, white, black, and purple, each of which has its own functional and aesthetic reasons, which we will delve into later. Green is by far the most common and is often used for several good reasons. Green has been around for a long time and has been a universal color code for PCB boards. Green is one of the least eye-tiring colors. So if a designer works on a green PCB for a long time, it is considered to be the least eye-tiring color. Green PCB printed circuit boards have higher contrast, making them suitable for quick identification of traces and residues. Resources that can be used to produce green printed circuit boards are widely available and readily available in large quantities. Since green is the color most people use, it is good for mass production and lowers the price of the product cost.
