The goal of the thesis was to learn about colorblindness and to study and create appropriate graphic content that would be suitable for colorblind people, but also useful for people with normal vision.
In order to make appropriate adaptation of selected graphical content – bus scheme, menu and three types of diagrams, the theoretical part examined the characteristics of human vision and color blindness, as well as various tests used to determine different types of color blindness.
To better understand what problems people with colorblindness face, an online survey was conducted to find out what people with color vision problems find most disturbing about graphic content. In the experimental part, the knowledge gained from the theoretical overview enabled the creation of adapted, redesigned selected graphic content. Namely, in the thesis, the bus scheme, the menu and three types of diagrams – a pie chart, a stacked bar and a line chart – were redesigned in different ways.
In the bus scheme, the presentation of the bus lines and legend changed, as did the color scheme, with the black and white variant omitted as one of the possible variants. The menu cover sheet menu, the headings of each food group and the list of allergens were redesigned. The presentation of the three types of charts was also redesigned, with the legends changed and enlarged, and the shape of the filling of each part of the chart, their line shapes, etc. were also redesigned. The second survey was conducted to evaluate the suitability of the redesigned mentioned graphical content. When creating for people with color blindness, the rules of appropriate graphic design and esthetics were taken into account.
