RGB vs CMYK
RGB vs CMYK
If you’ve ever worked with graphics or printed materials, you’ve probably come across the terms CMYK and RGB colours. These two colour models are used in different contexts and have different purposes, so it’s important to know the difference between them to achieve the desired results.
CMYK Colour Model
The CMYK colour model is used for printing purposes. It stands for Cyan, Magenta, Yellow, and Key (or black) - the four primary colours used in printing. CMYK is a subtractive colour model, meaning that it works by subtracting colour from white light. When all colours are combined, they create black. This is why black is referred to as the “key” colour in the CMYK model.
CMYK is used in the printing process because it produces accurate and consistent colours on paper. The colours in a printed image are created by layering dots of ink in different densities. The dots are so small that they blend together to create a smooth, continuous tone.
RGB Colour Model
The RGB colour model, on the other hand, is used for electronic displays such as computer monitors, televisions, and mobile devices. RGB stands for Red, Green, and Blue - the three primary colours of light. Unlike CMYK, RGB is an additive colour model, meaning that it works by adding colour to black. When all colours are combined, they create white.
RGB is used in electronic displays because it produces bright and vibrant colours that are well-suited to digital media. The colours in an RGB image are created by combining different intensities of light from each primary colour.
Why It’s Important to Know the Difference
Knowing the difference between CMYK and RGB colours is important because using the wrong colour model can result in colours that look different than intended. For example, if you create an image in RGB and then print it in CMYK, the colours may appear dull and washed out because the CMYK colour gamut is smaller than the RGB gamut.
Likewise, if you create a design in CMYK and then use it on a website or social media platform, the colours may appear too dark or muted because RGB colours are brighter and more vibrant.
In summary, CMYK and RGB are two different colour models used for different purposes. CMYK is used in printing, while RGB is used in electronic displays. Understanding the difference between these colour models is important to ensure that your colours look the way you intend them to, whether you’re designing for print or digital media.
