colours in the design

added by mila

We live in a wonderful word of colour. Colours are everywhere no matter where you look. We associate them with emotions, one make us calm the other burst our energy. Choices regarding colour often seem rather mystical, as many seem to base decisions on nothing other than “it looks right.” Although often told I had an eye for colour, the reason why some colours worked together while others did not always intrigued me and I found the study of color theory fascinating.

Most people are unaware of the science of colour, which starts with the twelve-segment colour wheel as a map to effective combination.

For a good and simple description of what the colour wheel is I am suggesting this page: http://www.colormatters.com/colortheory.html

But what I really wanted to mention here is the difference between RGB, CMYK and Pantone colours.

RGB Colour: This is colour based upon light. Your computer monitor and television use RGB. The name “RGB” stands for Red, Green, Blue, which are the 3 primaries (with green replacing yellow). By combining these 3 colours, any other colour can be produced. Remember, this colour method is only used with light sources; it does not apply to printing.

CMYK Colour: This is the colour method based upon pigments. “CMYK” stands for Cyan, Magenta, Yellow, and blacK (its what the K stands for). Using these 4 colors, most other colours can be achieved. Unfortunately, CMYK cannot reproduce the same amount of colours as RGB can, which is why yellow-greens sometimes look a bit muddy when printed.
This is the method used by printers the world over, and is also a clever way of mixing paints.

Pantone (PMS) Colour: This is yet another printing colour method. PMS stands for “Pantone Matching System,” and is a large list of specially mixed colours made by the Pantone Corporation. Instead of using CMYK to create colours, the pigments are created individually for purity.
  For example, if I wanted to use a Red-Violet colour, I’d pick PMS 233M. The colour would be made exclusively for my project and would always print exactly how I want.
  The only drawback to using PMS colours is that they’re only useful for projects with few colours. They’re also expensive.
