inverse colors , I couldn't find option in calibre

[richman]

I was wondering if calibre has a way to reverse colors on the screen on 505. So instead of white background with black letters, it would be black background with white letters.

I would love to see a setting in calibre that reverses the color scheme.

I think would be really cool as well.

I would expect a feature like this to be at the reader end rather than in Calibre.

As an example the Stanza eReader for iPhone/iTouch can invert the colors without Calibre having to do anything special.

You should be able to do it by putting

body { background-color: black; color: white; }

in extra css provided the source document doesn't specify its own colors.

Where would I put this code???

[richman]

thanks , love your calibre program!

maybe you could include option in the convert settings on same page with base font sizes about inverse colors or say something like " black background and white letters" . I too am not sure I would know where to find the settings css provided with the program.

Just put it in the extra css box in the look and feel section

Thank you, Kovidgoyal- Love your program btw...

body { background-color: black; color: white; }

I copied and pasted it in css and I didn't get it to work. Did I do something wrong? Using LRF format
I just highlighted it in red to show you exactly what I added.

I did it and 1st book I converted it did not work- I am sure I did something wrong, it was already in my 505,
but 2nd book I tried worked like a charm.

@richman Use epub, more likely to work with that

I know this is a very, very old thread, but I am wondering if someone might be able to help this work with a Paperwhite 3. I've converted the book and sideloaded it, but the background is white and so is the text.
Any help would be appreciated. Thanks.

Does anyone know how to make the margins the right color? I tried modifying the css to select the entire html but the added margins in the pdf remain white.

html, body, div, margin { background-color: black; color: white; }

is the CSS I used.

I unchecked all the filter style information because I already stripped all the color CSS from the epub.

Margins should be background colour.

This is the CSS I used and the resulting PDF.

The image shows that with the default settings and the CSS
body { background-color: black; color: white; }

The PDF contains large margins of the wrong color. I checked EPUB file to make sure it did not specify its own colors.
I removed any lines containing "border: currentColor","color:", and "background-color:" from the stylesheet.
