Hi, welcome to the fascinating world of PCB colors! Have you ever wondered why some PCB boards come in different colors other than traditional green, such as blue or striking red? In this tutorial, we will cover the PCB board's different color particularities and explore the reasons why we used such a different color combination.
An understanding of PCB board colors is helpful for the board manufacturing process, component configuration, and their uses in different projects and devices. We will also give detailed instructions on how any color affects your projects and how to select the best PCB color for your electronic projects. Let's get started.
The PCB color generally refers to the oil color on the board that is most intuitively seen when you get a PCB board and is primarily determined by the color of the solder mask or solder resist applied to the surface of the board. The solder mask acts as a protective layer that covers the traces of bare copper wires and safeguards the wires from short circuits and regular wear and tear. It protects the board from moisture, oxidation, dust particles, and other environmental conditions. It also gives a durable and colored finish to the PCB board and helps designers and repair technicians spot the copper wires easily.
Printed Circuit Boards, popularly called PCBs, are fundamental components in virtually any electronic device.
They typically serve as a physical foundation for most electronic components (i.e., resistors, capacitors, and integrated circuits). They appear in various colors, such as green, blue, and red. Some manufacturers are now developing them in rare colors like purple and pink.
PCB color choice has a much more significant role than one might initially think. For instance, green PCBs have traditionally been popular due to their reliability and cost-effectiveness. However, different colors can serve practical purposes, too, such as improving heat dissipation or aiding in component identification during assembly and maintenance.
Since green is the most popular solder mask color used in PCB board manufacturing, many people have always mistakenly thought that PCBs are green or that most of them are green.
Green adds clarity to the printed circuit board, and the green PCB will produce a sharp contrast with the white text, thereby enhancing readability. In addition, the green PCB surface treatment will reflect less light and reduce glare. It helps to read the different parameters and identify components easily. Therefore, the green PCB is essential for printed circuit boards that need a thorough inspection, making it a common color type of circuit board.
You'd find them typically used in various applications, including consumer electronics, industrial machinery, automotive electronics, and medical devices.
White PCB colors provide a clean and modern look, so you'd find them often used in consumer electronics, medical devices, and IoT (Internet of Things) gadgets. They are visually appealing and can enhance the overall design of a product. This makes their choice of color align with minimalistic and clean design aesthetics.
However, it's worth noting that choosing a white circuit board poses some challenges. Unlike other PCB colors that offer contrast, white lacks this distinct advantage. Therefore, white PCBs look particularly good in black screen printing. However, if we use a single headlight, it will be challenging to inspect and repair the white board.
If you are familiar with electronic products, you will discover that PCBs generally come in green colors, which is a result of several reasons:
PCB colors may impact the performance, aesthetics, and cost of the printed circuit board. This is why PCB manufacturers need to factor in some things when opting for PCB color. Below are some:
The color of a PCB does not necessarily have a significant impact on its functionality. However, there are some minor differences between different PCB colors.

A: PCB color plays a key role in electronic design. Aesthetics, component identification, and even heat dissipation are some ways PCB color can play a significant role in electronic design.
In addition, the color of the substrates, such as black PCB, purple PCB, blue PCB, and light PCB, is too dark, which will increase the difficulty of checking and repairing the motherboard, and the process is not easy to control. Use black PCB as an example;
Black PCB is most likely to cause apparent chromatic aberration due to process and raw material ratio problems in production, resulting in a high PCB defect rate.
The traces of the black PCB are not easy to distinguish, which will increase the difficulty of later maintenance. Many PCB factories do not use black PCBs. Green PCB substrates are available in the military industry and industrial control, products with extremely high-quality requirements. But the PCB color will not affect its performance in the slightest. It is not difficult for us to understand why the PCB color is mainly green.
