How to add color scheme to my Portal for Arcgis ?

[상묵__Sang-muk_Seok_석]

I want to make custom map using heat map in my portal.

However, when I change the color, there is just four color schemes. (pic 1)

Is it possible for adding or editing color scheme to my portal?

In order to visualize smooth color mapping, I want to create color scheme including transparency. (pic2)

Thanks for your help,

Seok.

I can reproduce this as well

From a look on ArcGIS Online we have the same options

I would look to log a request with Esri Support and request an enhancement request to add the abllity to select custom colors for the heatmap. (in both ArcGIS Online and Portal for ArcGIS)

Also you could put something in https://community.esri.com/community/arcgis-ideas?sr=search&searchId=b7a1a669-ac2e-4a4d-ba38-6179129...‌ as well
