ePub to azw3 paragraph background-colour
In an ePub to azw3 conversion I have some paragraphs with a background colour of #f0f0f0. This renders correctly in ADE, calibre reader and on my 8-greyscale Sony PRS-300, but it does not show in the azw3 - either on an actual Kindle PW or in Kindle Previewer. I have used default conversion options for the azw3.
Tweaking the azw3 shows that the background colour has been converted, so it seems it is just not rendered. Do I have to use particular shades of grey to work with Kindles?
