This design has been majorly simplified to just using text in its design so that usability is the main focus. Although text makes up the majority of the design, it has been used in such a way to create an illustrative appearance. The use of yellow and black in the colour scheme is to allow the contrast to make the text highly visible and easy to read. Large text has been used throughout to help the visually impaired. On menus the colours of the buttons have been alternated so that the user can distinguish between each, without getting them confused as one large button, as the elderly find it hard to make out edges and lines, this is where the contrasting colours come into play again.
