The Feature Info widget in ArcGIS Experience Builder developer edition (version 1.13) does not respect the style color of the web map's custom pop-up customized using arcade expressions.

Workaround

There is a known workaround for this issue. Create a variable and set the color within the variable. Then use the variable in the return. This method is honored by the Feature Info widget.

var title = `<span style="color:#ffffff">TITLE</span>`

return {

 type : 'text',

 text : `<div style="background-color:#3f540f;padding:5px;"><strong>${title}</strong></div>`

}
