Arcade supporting the font html tag

JaysonLindahl — Mon, 02 Jun 2025 13:42:36 GMT

I'm using the font html tag and the color attribute to return colored labels. I've read online that arcade supports this html tag. Here is my script:

var pct = $feature.PCT_NO;

var label = "Precinct " + $feature.PCT_NO;

var color = when(

pct == 1, "#FF0000",

pct == 2, "blue",

pct == 3, "green",

pct == 4, "orange",

"black"

);

return "<font color='" + color + "'>" + label + "</font>";

What is returned on the map is not colored text, but the actual html text in black.

Unfortunately, unlike ArcGIS Pro, you can't use formatting tags in a label in a web map. The way around that limitation would be to use a different label classes for each color.

For example, these labels were created using two label classes

The Deep label class uses the expression

if ($feature.Depth_ft > 30) return $feature.Depth_ft

while the Shallow label classes uses this expression

if ($feature.Depth_ft <= 30) return $feature.Depth_ft
