A guide to colour models
Pantone, CMYK, and RGB – why are there three colour models and which one should I use?
Your choice of colour model should be determined by what you intend to use the artwork element for.
Pantone
The Pantone Colour Matching System expands upon existing colour reproduction systems such as the CMYK process and enables the possibility to print special colours. This is achieved by using one solid colour ink (as opposed to the CMYK process, which generates a colour by mixing the four inks). However, it is also possible to combine the CMYK and Pantone methods on a single publication.
As different surfaces reflect light in varying manners, Pantone also takes into account the type of surface you are printing on (coated, matte or uncoated). Therefore, this is why you should always use a Pantone solid colour when colour is critical.
CMYK
Printing is based on the use of cyan, magenta, yellow and black (CMYK) ink instead of RGB light, and therefore produces a different range of colour.
When working with the artwork, the CMYK and RGB version will not look the same on your screen, as CMYK is meant to be printed onto a surface to produce the correct colours.
If you intend to print any of the artwork, then you must use the CMYK or Pantone options.
RGB
Scanners, digital cameras and computer monitors use red, green and blue (RGB) light to display colour.
You should choose RGB if you wish to use the artwork for electronic displays eg video, projector, DVD.
