Communicating using Color and Text

Information should not be exclusively conveyed using color. Colors can be used to organize information; however other, non-color dependent ways should also be used.  This can be done by labeling graphs and charts with the data information represented by color, using textures within graphs and charts so they are distinguishable from each other and/or having a key for your graphs and charts.


Example 1:



Bar graph with four bars representing number of respondents in different colors. The number of respondents is listed in three different locations and each is circled.



Example 2:

For ANY content where color differences are used to convey information, ensure that the same information is available through text or characters on the same page.


Circle graph with different patterns and alternating light and dark slices along with keys adjacent to each slice with a matching color/pattern block for that slice.



Example 3:

When using and creating required fillable fields, include either a warning symbol or verbiage indicating that the field is required instead of relying on color alone to indicate a required field.



Two email address fields with error indications using either an error symbol or text below the field stating "Email address required".
