Week 2 Question 2


Stop at the Red

The colour red has been consistently used as a signal to stop and can be seen as an example of functional consistency as it serves a function. By using a colour in new signs today, users are able to take their existing knowledge about the connotations of the colour red and apply it to the new design which enables them to use it effectively. for example, if you are driving down a road and see a red sign ahead but can’t see what it says, you instinctively know to proceed with some level of caution as the colour is so consistently used in road signs to signal a stop or caution such as traffic lights, stop signs and traffic cones.

Press Play

The play symbol is another example of functional consistency. The sideways triangle has been used as a symbol for ‘play’ since tape players (Lidwell, Holden & Butler, 2003. p.46) and has consistently been used for the same symbolic purpose for the last half a century. By new products taking this existing symbol and using it in new designs such as iPods, remotes, phones and TV’s it takes a person’s existing knowledge to enhance the usability of the new product, which as the reading states, “makes the new devices easier to use and learn”. (Lidwell, Holden & Butler, 2003. p.46)



Apple products can be seen as an example of aesthetic-consistency, making their products easily recognizable and a key part of the Apple brand. As stated in the previous post, Apple ensures its designs are consistents as it testifies to the ongoing industrial, economic and social values of the company, (Floch. 2000, p. 33). Apple has built its brand upon its clean, sleek and high-end design. They use consistent materials, colours, materials and applications as well as a consistent position of the Apple logo to group their products together and set expectations for the users such as high quality, beautiful displays and a sense of being a part of the Apple community.
