The user may define and edit a color palette for use with contours. In the [[SMS:Display Options|''Display Options'']] dialog, on the [[SMS:Contour Options|''Contours tab'']], pressing the '''Color Ramp''' button, opens the [[SMS:Color Options|''Color Options'']] dialog. Inside the ''Color Options'' dialog, selecting the User defined option enables the following options:
#REDIRECT [[SMS:Color Options]]
=== User Defined Palettes Frame ===
* '''New Palette''' – Create a new color palette. This opens the ''New Palette'' dialog, which is used to define a color ramp palette. The user selects a preset palette and the initial number of colors in the palette. The palette can be fine tuned once it is created in the [[SMS:Color Options|''Color Options'']] dialog.
* '''Delete Palette''' – Delete the selected palette.
* '''Load Palettes''' – Load palettes from an SMS defined [[SMS:Color Palette Files (*.pal)|palette file]].
* '''Save Palettes''' – Save all of the user created palettes  to a file using the format shown above.
 
=== Current Palette Frame ===
The color pallet selected in the ''User Defined Palettes'' frame is displayed. The user can select, edit, and drag colors in the ''Color Palette'' using the following tools:
* '''Create a breakpoint''' tool
** Mouse left-click – Creates new breakpoints
* Select an individual ''breakpoint'' tool
** Mouse left-click and drag – Changes the value associated with a breakpoint
** Mouse left double-click – Opens the ''Color'' dialog to change the color associated with a breakpoint
** Mouse left-click, then ''DELETE'' key – Delete the selected breakpoint
 
'''Value edit field''' – Change the value of a selected color. Changing a value will move the color inside the color palette window.
 
'''Edit Table''' – This button opens the ''Color Table'' dialog. Values and colors associated with each breakline can be viewed and edited. This dialog is useful for creating a palette with a logarithmic scale. It may be difficult to select colors very close to one another at the lower end of a log scale using the mouse left-click button, but the values can easily be specified in this dialog.
 
* Display Value As – Show the value of each color as:
** '''Percentages (0.0-1.0)''' – A percentage across the palette, with 0.0 being to the left of the palette and 1.0 at the right edge of the palette.
** '''Numerical Values''' – The actual value of each color. Each color will represent a value such as elevation.
 
===New Palette===
