Contrast (Excercise 11)

This is the 1974 Chair taken from http://www.flickr.com/photos/anyroom/sets/72157604058350087/. This is a good use of contrast. The base is made out of teak-wood, a natural material, and the actually seating is made out of acrylic, a man made material. The choice of material is ideal to highlight the attributes of materials. The acrylic is clear,transparent and allows other details to be seen through it, which lends off a lightness to the piece. On the other hand, the wood is opaque and blond in color, which suggests solidness.
The acrylic seat is composed of one solid piece that curves right in the middle of the base and back support.The legs of the chair consist of two geometrical parts that are easily connected together like puzzle pieces.

Here is an example of bad contrast. The link to this website is https:/.../CA1_webdesign_YvetteBad.jpg/65930790. The text on this website are relatively the same size and there are too many colors used which does not help create distinction between what is important and what is not.Different sizes of text would put emphasize and guide users to the important links .The overuse of color doesn't allow for "pop" effect against the black background. In this case it overwhelms the web page. It would have better to consider less color and using lower saturation of color would've create a better contrast to the black.
There is no contrast between the foreground and background due to the lack of tonal range that helps to create a sense of depth.
