PRIMARY & SECONDARY COLOURS The 3 Primary colours are RED, YELLOW and BLUE. No colours can be mixed together to make a primary colour. However, you can mix a primary colour with another primary colour to make a SECONDARY colour. If you mix RED with YELLOW you get ORANGE If you mix YELLOW with BLUE you get GREEN If you mix BLUE with RED you get PURPLE ORANGE, GREEN and PURPLE are SECONDARY colours.   COMPLIMENTARY COLOURS Colours which are similar to each other or close together on the standard colour wheel create harmony. Complimentary colours are colours that create contrast. These are the colours that sit opposite each other on the standard colour wheel.       4 PROCESS COLOURS The printing process uses 4 colours. These are the primary colours red, yellow and blue as well as black However, the red is a tone of red called MAGENTA and the blue is a tone of blue called CYAN. These printing process colours are often refered to as CMYK (the 'K' stands for black. If a 'B' was used it could be confused with blue or brown). Four seperate plates are made from the art work, one in each of the colours (CMYK). This is known as colour seperation. The printer prints each colour seperately on to a sheet of paper and all 4 finally make up the finished full colour image. The inks are normally printed onto the paper in order of lightest first: Yellow, Cyan, Magenta and Black last.       CLICK HERE FOR COLOUR INFORMATION on www.technologystudent.com
