The abbreviation PMS stands for Pantone Matching System and is a universal colour palette consisting of 1500 premixed colours. These colours all have a unique PMS color code. Because it is a fixed set of colours, you always have certainty about the right colour.
You can determine the PMS colour by using a colour chart, for example the online colour chart
that Pantone has made available. If you can't find a PMS colour matching your logo, you can also try an online converter. These converters give you recommendations of a PMS colour based on the input of a HEX or CMYK colour.
