How to add text to convey meaning

Find ways to include text that duplicates the meaning of the color or other sensory characteristic)

For instance, let’s say you have a table that includes all your guests to a meeting. You have marked in yellow those who are vegetarian, and in blue, those who are not vegetarian. Now you must find a way to convey this information to users who can’t see color.
You may do this in a variety of ways.
1. One way would be to separate the groups into 2 tables and clearly label them as Vegetarian or Non-Vegetarian.
2. Another option would be to leave the table as it is, and add either a (V) or (N) to each guest’s name. Also add a note that explains that names marked with a (V) are vegetarian and those marked with (N) are non-vegetarian.
3. One more option would be to add an asterisk only to those individuals who are vegetarian, and write a note explaining that those individuals marked with an asterisk are vegetarian.
