"When producing charts, great care must be given as to the colors used to represent different sections of the graph. One should avoid using colours which are too similar to each other, in case the chart is viewed by a color blind person unable to distinguish the colours, or printed in black and white. In the chart shown, we see that the only indicators as to which segment represents which category is the colour legend; as many of the colours are similar and contiguous, this leads to ambiguity and reduces the effectiveness of the chart. This problem could be easily mitigated by stating the percentages of each category both on the chart itself and on the legend, allowing the reader to successfully associate each segment with the data it represents.
