Allow customisation of chrome extension icon

[c-hri-s]

While I realise that a red shield is the logo of 2FAS, red is also the colour of notifications.
It's proving quite distracting to have a red icon pinned to my chrome shelf, I keep thinking I have unread notifications.

Would it be possible to allow users to customise the icon colour, or for you to provide some options which are perhaps a little less noticable.

Thanks
