Custom color ramps in ArcGIS Online?

[Anonymous User]

Any idea if it's possible to create custom color ramps or modify existing color ramps in ArcGIS Online? I know I can do it in Desktop or Pro and then publish it AGOL but this isn't exactly optimal for my needs.

Any help would be much appreciated.

Thanks

Hi Ian,

If you navigate to the Change style tab, you can select different pre-created colour ramps, or modify each specific fill colour and outline by clicking on the symbol to edit it.

Here are some instructions in the documentation: Change Style reference—ArcGIS Online Help | ArcGIS 

Let us know if you have more questions,

Hey Kelly,

Thanks for the response.  Unfortunately, I still couldn't find a way to change individual RGB values of the colors in the color ramp or create a custom color ramp.  However, I was able to find a workaround by updating the service definition using these instructions How To: Update the maximum record count for feature services in ArcGIS Online .  There's a drawingInfo parameter where I was able to modify the RGB values of each stop on the color ramp.

Thanks,

Ian
