Applying Johannes Itten's 7 contrast theory into information graphic



Johannes Itten defined in his book called "The art of colour", 1974 that there are 7 different contrast effects you can get in this world which are: 

  1. Hue contrast (the pure colour)- This results when pure colours are used in random combinations. White and black can further enhance the vivid. 
  2. Light dark contrast- This is when using different brightnesses and tone values of the colours. All colours can be lightened with white, and darkened with black.
  3. Cold warm contrast- All other colours appear cold or warm depending on their contrast with warmer or colder hues. The greatest effect is achieved with the orange-red and blue-green.
  4. Complementary contrast- When adjacent, they mutually intensify their luminosity to a maximum.
  5. Simultaneous contrast- When adjacent, they make noise, vibration.  
  6. Saturation contrast (quality)- Contrast between luminous and dull colours. Colours can be subdued by the addition of black, white, grey or complementary colours. 
  7. Quantity contrast- This is based on the opposition of coloured areas of different sizes. 
Here is an example:
Light dark contrast

Jacques Bertin's 7 variables



Currently reading a book called visual function. In this book, the author demonstrated Jacques Bertin's 7 variables. Jacques Bertin was a French guy who had experience on map making for many years. He was famous by publishing a book on the theory of "graphic variables", Semilogie Graphique. In this theory he defined there are 7 elements of visual information and their mutual relationship, which are:

  1. Place (position)
  2. Shape
  3. Size
  4. Value (light, size)
  5. Texture (within the shape)
  6. Hue
  7. Orientation (shape) /Direction (line)

    The golden section

    I am currently doing the golden ratio in one of the module. And I found this golden ratio is quite interesting and useful, so want to share with you guys in here.
    The golden section proportion is 1:1.618. This golden ratio can be applied in nature, human, art, architects etc....
    Here is a golden ratio software that i found: http://www.markuswelz.de/software2/index.html
