 If you do not know the grade 11 colour vocabulary and theory- this is a good time to review it.

 Color is a powerful design element. It impacts every design decision from pencils to automobiles,  Design success may be due more to color than to any other design element.

 A light source  An object  An observer

 Daylight  Artificial light  Mathematical simulation

 Smooth  Rough  Flat  Glossy  Curved

Which can be the human eye or a spectrophotometer

 the colour of light reflected from an object.  It is received by the colour receptors in our eyes. Other colours are absorbed

 A white object reflects all light.  A black object absorbs all incident light waves.

 An additive color mixture  has three primaries - red, green and blue.  White is the presence of ALL colors.  Black is the absence of ALL colors.

 In 1670 a dude named Sir Isaac Newton demonstrated that “white” light is truly a mixture of all “colored” lights.

 Stage lighting and the colors on computer monitors and television are additive.

 For more information on the additive theory 

 In subtractive systems, the mixture of all three primary hues (red, yellow, blue) ideally produces black.  Subtractive mixtures occur when pigments, paints or dyes are mixed.

 pigments or colorants absorb or subtract some wavelengths of the light striking them and reflect back the rest of the wavelengths.  The colors one sees are due to the absorption and reflection of the light by the colorants.

 A piece of fabric that absorbs the green and blue wavelengths of white light appears red because it reflects only the longer wavelengths.  The colors that are not absorbed are reflected from the surface.

 The subtractive color mixture  has three primaries - yellow, red and blue.  White is the absence of ALL colors.  Black is the presence of ALL colors.

 Color printing processes and color photocopy are based on the subtractive system of primary hues.

“If one says ‘red’ and there are 50 people listening, It can be expected that there will be 50 reds in their minds. And one can be sure that all these reds will be very different.” Josef Albers

 Color systems identify colour and arrange them so they can be described, identified, specified, standardized and coordinated.  They make it easier to see color and to describe it in terms of hue, value and chroma.

 For the designer, a system is just another tool to enhance color memory, allow communication and foster creative color play.

 Democritus  Plato  Leonardo da Vinci  Sir Isaac Newton  Moses Harris  Johan Wolfgang Goethe  Michel Eugene Chevreul

 Munsell identifies color in terms of three attributes: hue, value and chroma.  Ostwald uses a psychological approach.  CIElab provides a visually uniform color space  and is widely used in industry for color control.  NCS is based on color vision.  Pantone is a color specification and matching  system for color selection and communication.

PANTONE® is a color specification and matching system for the selection and communication of color.  It is a source of printed and electronic products for: › graphic design, › digital technology, › fashion, › home, › plastics, architecture, › contract interiors › the paint industry.
