AffPub colour display

[dbrear]

Hi all,

This is apparently a simple problem but I've no idea of the answer. Basically, why do I set one (RGB) colour in AffPub but see another on screen? And, before you leap to tell me, I don't think it's what you think.

Here's my partial screendump.



You can see I've set RGB 70,22,100, but the colour picker sees it as 75,6,100.

If I export the page to PDF the purple changes to blue —



— which the picker sees as 33, 0, 100. Noticeably different, but in fact this is what the AffPub RGB settings I used SHOULD produce. 

What I sent to my mate for discussion is this —

These don't actually look much different but they are. 

I initially assumed I needed to adjust my screen settings but now, having talked it through with My Mate Mike, since I can see the difference on the same screen, and since he can also see a visible difference on his machine, and has also checked the visible colour difference, I don't see how it can be that.

Incidentally, if I use (a very old version of) Paint Shop Pro, RGB 70,22,100 produces this —

— just like AffPub does, and if I save a pdf I get —



—so maybe it is something to do with my setup after all?

This all arose because I couldn't seem to produce a nice purplish purple in the PDF I want. It's easily remedied, by setting a redder purple, but now we both want to know —

— has anyone else come across this?

— how do we make it right?

Thanks in advance.

[If I produce a rectangle with the same RGB settings in AffPhoto I get —



— and the picker sees this as 74, 0, 101, which is quite different from the AffPhoto setting.]

Hi,

could you please provide

• a afpub document where the issue is reproducible?
• Screenshots of all relevant color profiles
  • Monitor (OS settings)
  • document setup
  • In case of placed images, source images 

In case your document uses any other profile except sRGB, this is partially expected behavior.

Hi, thanks for picking this up.

My settings are currently —

I've included this although as I say the problem appears to be my screen showing a different colour from what AffPub is displaying.

Many thanks for your screenshots provided!

This is likely due to the custom colour profile assigned to your monitor, through Windows -

Can you please select 'Add', then choose the sRGB IEC61966-2.1 profile (as shown in my screenshot) and then set this as the Default profile.

Now, restart the Affinity app and try exporting once again - does this resolve the colour differences in the export?

Well, I honestly didn't think it would, but it has!

PDF on the left, AffPub on the right. Thank you VERY much Dan! Colour picker picks up a VERY slight difference but insignificant.

I really did not see how it could be a screen problem, so good job someone knew better than me (not for the first time)

Isn't this an excellent forum? When I'm advising people to try Affinity products I always mention the help we get in the forums.

Take care,

David
