Question - Is there possible using background image and different color same time?

So i mean when i'm using own custom background image i would like to change when i opening email message then background color is example black and not white?

I think white it is too bright when opening this extension and message on night time so yeah is it possible doing that or no? if not, I would like to see it sometime in future if that is possible.


  • With the Custom button you should be able to create your own css to manipule the window almost any way possible.

  • how i doing that? what is that CSS code for it?

  • You can google it but CSS is the code used to produce or manipulate the entire layout of the popup window. I suspect you are not familiar with it - so I can take this as a suggestion and should it get more attention I can prioritize it.

  • I used google and found different skins CSS then i found hexa colors codes but i have no idea how i can change these emails background when i open email.

    I have now:

    * {

    --primary-text-color: #ff0000;

    --primary-background-color: #050505;

    --secondary-text-color: #ff0000

    --secondary-background-color: #ff0000;

    --disabled-text-color: #ff0000;

    --highlight-background-color: #ff0000;

    --hover-message-color: #2b303a;

    --error-color: #d04a48;

    --primary-color: #ff0000;

    --accent-color: #ff0000;

    --icons: #ff0000;


  • So those are CSS variables, if you want to target specific areas in my popup you must find the node id like such, this will target the open email and you set the background to orange.

    #openEmailMessages {

    background: orange;
