Colour shift in the display - white displays as pale yellow

[Stephen_H]

Help. Publisher on Windows is suddenly displaying all objects with a warm, yellow shift. It's so bad, that pure white appears like a 30% yellow. The artboard is pure white, so I know it's not my monitor. All I can imagine is that it's a colour profile issue that is forcing objects to display differently on screen.

If I make a white object (like my screenshot), it appears cream on screen, but if I print it to my laser printer, I get a blank page. Same thing if I export a PDF. My white object appears white. This means that white is still white, it's a representation on screen.

This screems colour profiles to me, but everything is set to factory defaults. It also doesn't matter if I use a CMYK, RGB or even Greyscale documents. They all display white as cream.

Yesterday, I registered my app/device on my Affinity account. Is it possible that registration has forced new settings into my app?

The preferences dialog you show are for the entire application. Go to the Document's Colour tab in the Document's set up.

Hi.

It's in every document I open - new and old.

It also doesn't matter what colour format I choose for the document... CMYK, RGB, or even Greyscale. The display is identical.

It even displays this creamy colour in my swatch palettes.

Even placed images get changed. (This example of a white bottle actually has a pure white background)

This problem is definitely global and not limited to a single document.

I'm attaching the document as well as the exported PDF which comes out fine.

Both look exactly alike, no yellow/cream colour cast.

I am on Mac OS 11.6

I use the bog standard monitor profile for Mac. 

Sorry but I don't know enough about Windows to help further.

I only opened the Test.afpub one but I do not see any color cast in it either. I think the link to the topic @walt.farrell posted explains what is wrong & how to fix it.

Walt... you're a genius. Your answer sent me in the right direction.

I discovered this problem wasn't limited to Publisher - but involved displaying all imagery through Windows (Except for PDFs, go figure). It turns out that I only get this problem when I have a second monitor plugged in with the display setting on "Second Screen Only". I change it to Duplicate screen" and everything is fine. I'm guessing my Dell monitor is forcing an uneccessary colour display profile to be used.

So this turns out to be a Windows issue instead of a Publisher issue. This is new and has never happened before (I know, I use "Second Screen" every day at work)

Thank you everyone who helped me solve this puzzle.
