Anyone able to help with this?

I see only 1 png here so if I load that into Sumatra the rh half will be dark and the lh will be light others would need a safe link to the source to see if it is a problem file ?

Hi, that is a screen shot of the same PDF in Sumatra and Adobe side by side.

Agreed it seems to be localised to SumatraPDF colour handling,
since MuPDF (SumatraPDFs engine) will show it as expected

best to raise a bug report for @kjk on

This issue was fixed in recent version 3.2
