If you need to use six or more colors to represent the data - it might feel cluttered or overwhelming to the viewers. Consider consolidating categories or breaking up the chart into multiple smaller charts as described above. -- A 3:1 contrast ratio is required for figures if a person must perceive a graphic in order to understand the content (e.g., colored lines in graphs, points on maps). However, text that is embedded in a graphic must meet a contrast ratio of 4.5:1 unless the text is incidental or there is no way of presenting the graphic with sufficient contrast without undermining the meaning.
