# Using Legends

Tableau Reader uses colour, size and shape to encode the view with additional information. For example, the marks can be broken into multiple colours to represent different regions and shapes to represent different products. Then those same marks could be assigned different sizes to represent the profit margin. Each type of encoding has a legend. You can edit these legends to use different [colours](https://help.tableau.com/current/reader/desktop/en-gb/colors.htm).
