CMYK colour mode is four different ink mixed in colour printing. Cyan ( Blue ), Magenta ( Pink ), Yellow and Black is referred as CMYK, which is used in general paper printing processes. Unlike RGB colour mode, CMYK absorbs four colours into white paper surface, which it creates unsaturated colour on final printed product. Whilst the production encompass the final colour via running through four different components : Cyan->Magenta->Yellow->Black, the colours absorbs each component run after run, which the tiny particles of each colour produces a block of a colour to a human eye in halftoned form. Thus, CMYK produces wide spectrum of colours but not in saturated form.
RGB colour mode is combination of three primary colours : Red, Green, Blue. This value represents the colours that are exhibited through electronic devices such as monitors, television, cameras and other forms of computer systems. It uses lights to pass through the primary colours, using the reflections on the human eye of these colour to represent multiple colour spectra on screens. It is a complete opposite process compared to the any colour modes that is applied on ink, paint or other method that uses white as a main base material. Due to the use of light wavelength to create the colour schemes, RGB creates strong vibrancy in colour. However, this value is only for viewing purposes through electronic system, not to translate into a physical material form.
Pantone is also knows as PMS : Pantone Matching System, which itself is multiple colour schemes used in various industries comprises a painting/colouring as a representing method. Using 14 different colour pigment mixes, Pantone uniquely created standard colour matching system to unify the colours in different manufacturing sectors. Since then, Pantone has been an ideal standard colour reference to industries and businesses. Although the current pantone values are broad, it still does not depict the colours processed via CMYK mode.
