We all know that "design" simply means the "look" of a particular object.The art or profession of using design elements to convey information or to create an effect.

Conveying information- For example, the buttons on your cellphones.




Notice that there are little pictures of phones coloured in green and red. Clicking on the green button simply means to answer an incoming call while the red one means rejecting a call or hanging up after you have finished making a call.

Why red and green.

RED- The colour red dontes emergency or danger. Red is the colour that grabs our attention very much. Stop signs and stop lights are red to get the drivers' attention and alert them to the dangers of the intersection. When this application is applied to cell phones, it simply means to "stop" a call or to "stop" an incoming call.

Green-Green has a totally different meaning to that of red. While red donates an impression of stopping, green on the other hand gives us an impression of "going", the permission to proceed. Green also donates stability and balance and red contrasts green, grabbing attention and awareness. When this application is applied to cellphones, it simply means to "answer" an incoming call.






Not every phone has the red and green button. But, they do have buttons whereby we follow the directions given on screen and punch them accordingly. =)
