Customize color of included point icons
It would be nice if we could change the color of a point icon in the new web map viewer. Some of the icons come in different colors, but so many of them only come in gray, or one color, and it'd be nice to be able to represent something in different colors to make reading the map easier.
For example, it'd be great if I could change the Knox Box icon (a key) to be a red background instead of gray, to match the logo for Knox Boxes, and maybe the sprinkler icon to teal to match the maps I'm digitizing. Ultimately, it'd be nice to make it so all these gray points can be made different colors to be more easily distinguishable from each other.
You can do that in Map Viewer. If you publish those as a web style to your organization (detailed steps in the blogs below) you can adjust those colors. For this you would want to use Shape Marker symbols so the colors are swapped when replaced. if its a Picture Marker symbol the colors will be masked and not swapped.
Those symbols are classic symbols that we brought into Map Viewer from Map Viewer Classic to help users migrate. These symbols dont support any color change just like in Map Viewer Classic.
If you want this Style with Vector capability you can download the vector sample here:

I also published a version under esri_webstyles account and if you set up a group to contain your web styles you can go Add Item > and search for owner:"esri_webstyles" or search for Government.
And then picking one of your examples staircase
The upside of using this version instead of the image URL
1) Usually the hosting servers are not configured correctly and you will get a CORS error
2) If the browser cache is cleared you have to re-link the images
3) If the image url changes this can break the map
4) its still just a picture marker symbol so the color controls you want wont be supported.
Using the web style on the other hand
- No worrying about CORS
- Symbol gallery is hosted in Online and available to all memebers across your organization. No need for each user to upload/link the same images
- Symbols are written into the web map so if the Web Style is deleted the map styling will not be impacted.
- Vector support so you can change the colors like the above image sample.
