Colour lesson – CMYK / RGB. What do these letters mean?

So what is CMYK and RGB colour?

Simple!

CMYK = Cyan, Magenta, Yellow and Black (Black is K and stands for Key plate)

RGB = Red, Green, Blue

We use CMYK for printing. These four coloured inks combined make up all the colours you’ll find in everything printed – Magazines, Brochures, Flyers etc. CMYK is subtractive, just like paint as you add more colour, eventually everything will turn black. So next time your reading a Magazine / Flyer take a close look at the image and try to see if you can see the dots making up the colour.

RGB coloured light is used for screens – for example your TV, Mobile, Tablet, SatNav & Camera’s display RGB. More colours can be produced than CMYK. RGB is additive, just like the way real light creates colours. You start with black (darkness) and as you add lights of more colours you eventually get white (all colours shining together like a regular lightbulb) RGB can create millions of different colours using the spectrum of light.

FACT ALERT – CMYK dates back to 1906, when the Eagle Printing Ink Company used this process for the first time! RGB aws used in TV’s back 1928!!!
