To make it easier to distinguish between steps in a workflow, or simply change the look and feel of a workflow in graphical view, you can apply fill color to one or more steps.
To add a fill color to workflow steps:
In the Workflow Step window of an open step, click the Layout tab.
To select a single workflow step to fill with color, right-click the step, and then click Edit on the shortcut menu.
To select multiple steps to fill with the same color, press
Ctrl,click all of the steps to which you want to add color, and then click Edit on the shortcut menu.
Click the Display Settings tab.
Use the color selection features on the Swatches, the HSB tab, or the RGB tab to specify a fill color for the step.
Click anywhere on the Layout tab.
The selected steps are filled with the color you specified.
