Flashing Dot When Item Selected - Dashboard

Question

Hi, can someone tell me how to change the size and color of the “flashing dot” that appears when you make a selection from a selector in a Dashboard?

I have looked and found where I can modify the flash rate by editing the JSON file, but not the size and color.

Thank you so much, 
Fen

UPDATE: Found another way to do this just by changing the "Accent color" in the Custom theme settings (because that also seems to dictate the color of the flashing halo around the point when it's selected) and by poking around in the ArcGIS Online Assistant and making some edits in the JSON.

I'm not seeing any options at all to edit Map colors in my Dashboard... is this something that may have moved or gotten phased out in a recent update?
