You have probably come across these terms before. Many are familiar with the terms and know a little bit about what they actually mean. Therefore, it seemed useful to explain the different terms and immediately tell you what you use the different color groups for. Let's start right away. It seems quite difficult, but actually you can easily tell them apart. First, I'm going to break it down completely, then we'll look together at what they all mean. If you break it down completely, it comes down to the following:

• CMYK  - Print

• PMS  - Print

• RGB - Digital use

• HEX - Digital use

• YUV - Digital use

• LAB - Print

So in short, you have two for printing and two for all digital use. 

There are of course many more color types, but these are the most commonly used and therefore also the most important to know.

CMYK (CYAN, MAGENTA, YELLOW, KEY)​

You have arrived at the section about CMYK, but what exactly does CMYK mean? The letters stand for different primary colors that are used to create all other colors. 

The C stands for Cyan, which is a light blue color, see here on the side. Next, you have the letter M, M stands for Magenta, and Magenta is a dark pink color. Then comes the Y for Yellow, yes... yellow is and remains yellow. And then you have the letter K, K stands for Key, this color is not quite the deep black color we are all used to from the color black. It tends slightly more towards Anthracite, but again, not completely. 

CMYK is the most commonly used color type for printing. But the big difference between CMYK and PMS is that PMS is the same worldwide, but CMYK differs per country. The colors then turn out differently. That is why a universal color language was devised, namely PMS. 

PMS (PANTONE® MATCHING SYSTEM)​

As you probably expected, we are now at the PMS color type. As I mentioned in the previous chapter that CMYK differs per country, PMS does not. 

This is also an abbreviation for other words. PMS stands for Pantone® Matching System. This means that these are fixed colors that are established worldwide.

PMS is a color system primarily used by graphic designers and printing companies. Because the colors are fixed, printers are able to deliver print work that meets the customer's requirements. By using PMS colors, you are sure that your print work will be printed in the correct colors. PMS colors are marked with a unique number followed by a letter. The letter indicates the type of paper. For example, 'C' stands for coated, 'U' for uncoated, and 'M' for matte. 

There are special color fans for PMS that designers, graphic designers, and printers use to determine the correct color. 

RGB (RED, GREEN, BLUE)​

The most famous color system is RGB, also known as Red, Green, and Blue. These colors are especially effective on screens. Since every 'LED' screen is built with these three colors, this ensures that the colors are pure and clear. 

The RGB color system is a color coding method, a way to express a color using a combination of the three primary colors Red, Green, Blue, based on additive color mixing. The amount of each primary color required to obtain the mixed color is expressed in a number that usually consists of 8 bits and can vary between 0 and 255.

HEX (​Hexadecimal)

HEX is the abbreviation of Hexadecimal, a number system used in computer science. In the HEX system, numbers from 0 to 15 are represented using 16 different characters (0-9 and A-F). This allows colors to be represented in a standardized way in the computer world.

The HEX color system is widely used in web design and graphic design. Colors are defined by a combination of six hexadecimal digits, which represent the amount of red, green, and blue in the color, respectively. The first two digits represent the amount of red, the next two for green, and the last two for blue. Each color can therefore be represented by a unique combination of these six digits.

The use of HEX codes ensures that colors are displayed the same on different computers and devices. It is therefore a useful tool for designers and developers to use and communicate colors in a consistent manner.

Lab Color System

The Lab color system is a device-independent color model that represents a color based on its perceived color properties. It is a three-dimensional color space that uses the L*a*b* color model. In this system, the L* axis represents lightness, while the a* and b* axes represent the position of the color on the red-green and yellow-blue axes, respectively.

One of the main advantages of the Lab color system is its ability to represent colors that fall outside the range of other color systems. It is also used in color management systems, where it can be used to convert colors between different color systems.

YUV Color System

The YUV color system is a color space used in video and digital image processing. It is based on the YUV color model, which separates the color information (chrominance) from the brightness information (luminance). In this system, the Y axis represents brightness, while the U and V axes represent the position of the color on the blue-yellow and red-green axes, respectively.

The YUV color system is used in video compression, where it can be used to reduce the amount of data needed to represent a video signal. It is also used in digital image processing, where it can be used to separate color information from brightness information.

Conclusion

In conclusion, understanding color systems is essential for professionals in various industries such as graphic design, printing, and web development. Each color system has its unique characteristics and applications, making it important to choose the right color system for the task. By understanding color systems, professionals can create accurate, consistent, and appealing designs that effectively communicate their message.
