Double-click any color bar to edit its color.
To move themes up and down in the list, or within their category, click the theme to move and use the arrow buttons. Vertical positioning indicates the display order of themes in the model.
Copy, edit, or delete themes using the tools above the theme list.
Click (Export Themes) to export theme definitions.
