The main portion of the Boundary plot attributes window and FilledBoundary plot attributes window, also known as the Boundary colors area, is devoted to setting material boundary colors. The Boundary colors area contains a list of material names with an associated material color. Boundary plot and FilledBoundary plot colors can be assigned three different ways, the first of which uses a color table. A color table is a named palette of colors that you can customize to suite your needs. When the Boundary plot or FilledBoundary plot use a color table to color subsets, they selects colors that are evenly spaced through the color table based on the number of subsets. For example, if you have three materials and you are coloring them using the "xray" color table, three colors are picked out of the color table so your material boundaries are colored black, gray, and white. To color a Boundary plot or FilledBoundary plot with a color table, click on the Color table radio button and choose a color table from the Color table menu to right of the Color table radio button.
If you want all subsets to be the same color, click the Single radio button at the top of the Boundary plot attributes window and select a new color from the Popup color menu that is activated by clicking on the Single color button . The opacity slider next to the Single color button sets the opacity for the single color.
Clicking the Multiple radio button causes each material boundary to be a different, user-specified color. By default, multiple colors are set using the colors of the discrete color table that is active when the Boundary or FilledBoundary plot is created. To change the color for any of the materials, select one or more materials from the list of materials and click on the Color button to the right of the Multiple radio button and select a new color from the Popup color menu. To change the opacity for a material, move Multiple opacity slider to the left to make the material more transparent or move the slider to the right to make the material more opaque.
The Boundary plot attributes window contains a list of material names with an associated color. To change a material's color, select one or more materials from the list, click the color button and select a new color from the popup color menu.
