How to make your own color-ramp in ArcMap:

 

1) Open up a project

2) From the "Tools" menu, select "Styles" and then the submenu "Style Manager"

3) If you want to edit/create a color ramp for your own user profile, expand the directory with "your_user_name.style". Otherwise, to edit one of ESRI's built in styles, open the directory with "ESRI.style"

4) Select "Color Ramps"

5) To edit an existing ramp, double-click it. To make a new ramp, right-click in the color ramp box, and select "New". The following choices are given:

Choice Name
Definition
Random Color Ramp Creates a ramp based on limited criteria (min/max color, hue, and saturation values)
Multi-Part Color Ramp Assemble a color ramp using a combination of Random and/or Preset and/or Algorithmic Color Ramps, or multiple ramps with varying criteria. Use Add/Remove & Up/Down Arrows to adjust.
Preset Color Ramp Standard color ramp with 13 user-defined values. Select colors from color table, or click "more colors" to input RGB or CMYK or HSV colors. Combine multiple Present Color Ramps to use more than 13 values.
Algorithmic Color Ramp True color stretch between 2 user-defined (color table or RGB) values.

6) Select "OK" then "Close" to finish

7) When characterizing symbology in the ArcMap Layer Properties: Symbology window, your user-defined color ramps will appear in the choices listed. Mine appeared at the very top of the list, yours might vary.
