I have just started Chrome development. I understand everything runs through the manifest.json file.

I have both production and development extension installed. However, I want to change the icons depending on whether its production or development. This will help me visually distinguish what version I am testing with.

How can I achieve this?

Currently below are my icons thats used for both production and development

manifest.json

"icons": {
 "32": "favicon-32x32.png",
 "48": "favicon-48x48.png",
 "128": "favicon-128x128.png"
},
