Editing single-value pseudocolor tables

You can create and modify pseudocolor tables (PCT) in the PCT Editing window. On the Maps tab, a pseudocolor layer appears as an icon with vertical color bars followed by layer-file information. A PCT is generated only for an image layer that is designated as a PCT layer.

On the Single Value tab, under Predefeined Pseudocolor Tables, you can apply a preset PCT to your image. This can give you a starting color range from which you can further edit the colors, as necessary.

Under Current Pseudocolor Tables, the table displays color values for the active PCT. In the Breakpoint, R, G, and B columns, you can edit the breakpoint and RGB values, respectively. Under Color Selection, you can also modify the output color of the current PCT.
