After installing the extension, change the backglound color of the left panel as: rgb(30, 0, 68), where Red: 30, Green: 0, Blue: 68. Or to any other colour.
If you want to set the background color of the email as the theme colors (without white background), you need to push "Alt" and in top menu enable "Appearance (View) --> Message body as --> Simplified HTML". After than your need to change the default colors of the background and text of the e-mail message in "Preferences (Settings) --> Formatting tab --> HTML - Styles", don't use default colors, change background: Red: 30, Grren: 0, Blue: 68; text: Red: 205, Grren: 202, Blue: 230.
And I don't know how to change the background color of the Address Book tab. It will look like a mixture of my theme and the default dark theme.
