Rated 2 out of 5 stars

Has potential, but results a bit hit or miss.

Colours are weak/pastel and in the selection box are all so weak they appear almost the same.

Zebra stripes won't disappear in Thread window, and in compose window, FROM an TO boxes are not coloured.

What I expected/wish for is to be able to have Folder, Thread and Message windows, and the Compose window and the Text area, to have the same background colour depending on the account.

I use Border Color extension to help ensure I send from the correct account but it seems to conflict with this, but it is much better at showing the account being used in the compose stage

This review is for a previous version of the add-on (2.0). 

Problems being Addressed

Background colors are intentionally weak/pastel. Release 3.0 will fix zebra stripes in thread pane and from/to coloring in compose window; and will provide options for coloring and styling messages in thread pane; and will provide much clearer indication of the identity/account that the message will be sent from.
