How to set inverted (dark) background with original images?

[pilot3000]

Hello,
How to set inverted (dark) text background, but with original images?
I use SumatraPdf v3.5.2 and v3.6.16779.
With inverted images SumatraPdf is useless for me.

Thanks in advance!

Not possible

MuPDF, which SumatraPDF uses for graphical rendering, allows for 3 different states one is a foreground "tint" one is a Background "tint" and the other is both reversed (inverted) thus it has no themes or styles. PDF or ePub the results are the same since earlier versions. So for changing the PDF colours you need an EDITOR like Adobe readers, but I cant show you that as this is an eBook.

The comics book is different as there inversion is not applied the surround is simply black

How can I change background color, For Example:
BackgroundColor = #bab8b8
in Darker mode in version 3.5.2 ?

It applies BackgroundColor to Light mode, whose border is 'too light'.

To write your own dark themes such as the one shown you will need the latest pre-release from downloads
using somebody's suggestion for DarkGreen is easy on the eye.

I did something like this (modified darker) in version 3.6.+, but since this release is not final (not official) I tried to do the same in 3.5.2.

Could you please upload your settings file?

I created my own Theme called 'Darker_OK':

`Themes [
[
#name of the theme
Name = Dark_OK

#text color
TextColor = #000000

#background color
BackgroundColor = #9c9a9a

#control background color
ControlBackgroundColor = #9c9a9a

#link color
LinkColor = #444c85

#should we colorize Windows controls and window areas
ColorizeControls = true

]
]
`

It works, but there is some problem - I didn't find how to add borders on the left and right:

Please advise what to do.

the borders are either one of two settings for between 1 to 3 colours as I have shown in some cases then the experimental
main Fixed UI setting is set any 1 or 2 or 3 colours via

GradientColors #123456 #7890ab #cdef12

The Alternative is change the main window colours
