1. Green PCB

Green PCB is the most popular color. Therefore, many people have been mistakenly thinking that PCB is green or mostly green. Green increases the clarity of PCB because green PCB will create a sharp contrast with white text, thereby enhancing readability. In addition, the green PCB surface treatment will reflect less light, which helps to reduce glare.

2. White PCB 

White PCB looks clean and neat in various environments and is becoming more and more popular. However, since white PCB easily hides traces, white PCB is still not the first choice. But white PCB looks particularly contrasting in black screen printing.

3. Yellow PCB

Yellow PCB was used more before, but it is not so practical now. Yellow PCB can quickly meet different needs such as style, cleanliness and visibility. Yellow PCB has an obvious disadvantage: poor contrast with traces and screen printing.

4. Blue PCB

Blue PCB is considered a thick board for labeling because it provides significant screen printing contrast. This PCB color is not as eye-catching as green PCB, black PCB or white PCB, but blue PCB is the first choice of PCB color because it provides an excellent aesthetic choice. Blue PCB is better to be installed on LCD because blue PCB does not produce sharp contrast edges and bright background colors.

5. Red PCB

Many PCB manufacturers are keen to adopt red due to some advantages of red PCB. Red PCB provides excellent visibility and clearly defines the contrast of traces, planes and blank areas. Silk screen looks very beautiful against the background of red PCB.

6. Black PCB

Black PCB is as popular as white PCB. These two PCB colors produce low contrast and can easily mark important components. However, the main disadvantage of black PCB and white PCB is that specific details may focus light and have small shadows. This shadow makes tracking difficult. Therefore, black PCB should not be used in various high-temperature applications because black PCB may discolor the silk screen. Moreover, black PCB board is a mixture of cobalt and carbon, and its conductivity may be relatively poor.
