Using ArcGIS 10.4 and looking for a diverging color ramp for your map features?  Try the Diverging Color Ramp Addin.

This addin enables you to intelligently apply a dichromatic color ramp to feature layers containing points, lines, or polygons in ArcMap 10.4. The addin is similar in capability to the smart mapping tools in ArcGIS Online.  The addin is useful if you need to display data with values that diverge from a specific threshold value which you define.  Click below for more info on the tool.
