Created attachment 129922 [details] Example of a background-less html email on a dark theme It would be really helpful to have a switch per email to temporary change the background to white when using a dark theme, since some email are designed ( wrongly ) assuming the background is white and they are difficult to read in this way. STEPS TO REPRODUCE 1. Set a "dark" theme 2. Open an HTML email with trasparent (or no ) background which assume a white default background OBSERVED RESULT The background of the email is the one from the dark theme, but the email is not designed for it EXPECTED RESULT There is an option to temporary set the email background to white ( IIRC I've seen something similar in the gmail android app ).

Your idea is really good. It would be helpful. Currently you can make sure that kmail doesn't change the background color of messages by checking this option: Settings -> Appearance -> Colours Check "Do not change the color of the original HTML email" With it active, if the email has a white background, it will be displayed correctly. I hope this can help you.
