Legend Preferences

The following legend options can be set in File > Preferences > Colors.

By default, the transparency option is turned on. Turning off transparency along with choosing the right background color helps to better visualize the legend if its overlapping the model.
Background Color
When the transparency option is turned off, select the legend's background color.
Divergent Color
By default, divergent color option is turned on. This can be turned off to get normal contour color.
No Result Color
The elements without contour results can be displayed in user-controlled color.
