From an open Cmap:
You can change the color of the background of concepts, linking phrases, and the Cmap itself. You can also change the color of linking lines and lines that border a concept or linking phrase. To change the color of a selected linking line, select Styles... from the Format menu. (Notice that a linking line may have a different shape than an actual line. More information on different types of linking lines can be found in the help section Modify Linking Lines.)
From the "Styles" window, "Line" tab:
You can use the Color button to change the color of the selected line.
Once the Color button has been clicked, a palette of common colors is revealed that you may select from. No Fill will change the color of an item (other than the background) to transparent. Click the More Colors... button to choose a particular color not shown in the palette.
The "Choose a Color" window opens to the Swatches dialog where you can pick a color from an expanded palette. The color currently chosen appears in the Preview panel. Selectable swatches of previously chosen colors are under the Recent: heading. Click the HSB tab at the top of the window to further explore your color options.
The HSB dialog opens, allowing you to select a color using Hue, Saturation, and Brightness values. You can click inside the color square to select a color value. You can also drag the slidebar with the mouse, specify numeric values in the text boxes, or use a combination of features in the HSB dialog to select a color. The HSB dialog shows corresponding RGB values. You can click the RGB tab to fine tune these values.
The RGB dialog allows you to select a color by adjusting the color's Red, Green, and Blue values. You can use the slidebars, text boxes, or a combination of features in the RGB dialog to select a color. After you have chosen a color, click the OK button to observe the change in color of the Cmap item.
When you return to the Cmap, the item you selected will be in the color you chose. You may also want to change the color of other Cmap items to the selected color.
You can change the color of multiple Cmap items at the same time. A way to select multiple adjacent Cmap items is by clicking and holding down the mouse button to drag a selection rectangle over the items. By holding down Ctrl and clicking on items, more than one non-adjacent item may be selected. A combination of clicking and dragging selection rectangles, all while holding down the Ctrl key, can capture both adjacent and non-adjacent Cmap items into the selection. (Alternate ways of selecting Cmap items can be found in the help section Nested & Merged Nodes.)
Once you are finished selecting Cmap items, select Styles... from the Format menu.
