Changing colors and legends using the "Choose Color Ramp" dialog box changes the entire color scheme. You can change the colors associated with individual attributes in the visible theme, raster outputs, and vector themes using the "Color" dialog box.
To display the "Color" dialog box, double click on the legend color you want to change in the "FARSITE Simulation Legend" dialog box. Simply click on the color you want from the "Color" dialog box and click OK. The landscape should automatically redraw.
You may want to use colors other than the Basic colors: displayed. For example; If you plan to display your landscape in a medium with a defined color palette such as the Wide World Web. Or, you just want more choices of greens. To expand the "Color" dialog box click the Define Custom Colors >> button.
If you plan on making a GIF image of your visible theme, limit your red, green, and blue values to 0, 51, 102, 153, 204, or 255. Any combination of these values will give one of the 216 "browser safe" colors. This means colors won't shift or similar colors become the same when you make the image into a GIF.
If the landscape window is currently displayed and the new color(s) are not displayed, select View > Redraw 2D Landscape to re-display it with new colors.
NOTE: redrawing the screen may take some time for large or high resolution landscapes because all colors are re-assigned by reading the landscape file from disk.
BE CAREFUL: Redrawing the landscape during an active simulation will erase all fire perimeters and other designations on the old landscape.
