The Symbology functionality (from the My Layers window) is based on styles supported by GeoServer. Please see GeoServer User manual for more information.
Coverage symbology
You can Add or Remove a rule to the table. To decide how to set up appropriate rules, it is often helpful to first look at the Statistics. You can then choose the color scheme representation under Type. The default Type is interpolation (ramp), with the others being Intervals and 'Values. For help in selecting the appropriate type, please refer to ColorMap type. If Intervals is selected, the first rule in the table should use the no data value of the coverage.
Click Apply to use the new rules.

You can Add or Remove a rule to the table.
To modify a rule, select the rule and change its Filter or Graphic.
To modify the filter click Filter. In the Filter window (Figure 2 center), select the property, condition and value to be used. If there is more than one condition in a Filter window, they must be connected by selecting a proper condition from the dropdown list in the toolbar.

To modify the graphic click Graphic. In the Graphic window (Figure 2 right), select the marker, its color and its opacity.
To apply new rules click Apply.
