Libreoffice 220.127.116.11 for macOS seems to have 2 issues with colour profiles:
1. when viewing an inserted PNG image, the view shows paler colours than the original PNG
2. when exporting PDFs (lossless images, pdf/a), the image in the PDF shows overly saturated colours compared to the original
MS Word 16.11.1 for macOS shows consistent colours in the editor view as well as the PDF export.
See below for steps to reproduce including test images, docs and pdfs.
Steps to Reproduce:
1. Take source docx which has inserted images, or create one as follows:
a. create new doc in ms-word, insert test png p5_we_hsb_final.png, don't copy/pase
b. save docx - this is the source doc
2. open docx in ms-word, save as PDF (print not web for higher fidelity options)
3. open docx in libreoffice, save as PDF (lossless images, pdf/a)
4. observe the editor views in ms-word and libreoffice - note different colours
5. observe PDF (eg in preview) - note difference in colours
6. observe original PNG image - note colours are the same as the ms-word editor view and PDF export - but different to the Libreoffice editor view and PDF export
colours should be consistent across editor view and PDF export and the same as the original image
User Profile Reset: No
see attached files to help reproduce the error
1. source PNG image
2. source docx with inserted PNG image
3. PDF from ms-word
4. PDF from libreoffice

first recommended to put on ask.libreoffice then here on bugzilla by libreoffice
also tested with latest fedora linux (27) with latest libreoffice 6 form libreoffice.org using flatpak (because fedora repos won't have lo6)
pdf exports show same inaccurate colours

doesn't show any noticeable difference between the 2 exports for me, following the instructions provided.
However, I did the same test with LO603 and could see a difference.
The enclosed screenshot shows the comparison between the original export from Word 16.11.1, my LO 6.1 alpha master build, and LO603

Tariq: can you try with a daily build to see if you still reproduce the issue ?
If not, then it would appear that the problem has been fixed in master.
Sadly it didn't work.
I tried LibreOffice dev version

I've uploaded the editor views and the resultant PDF. So to summarise:
* libreoffice 18.104.22.168.alpha0+ editor view shows the incorrect colours
* libreoffice 22.214.171.124.alpha0+ export PDF shows the incorrect colours

comparing PDF exports from LO-61-dev
* When I am using only my MacBook Pro 2015 15" .. the colour difference between the exported PDFs is negligible (but the editor display colours are different with LO being paler than original PNG)
* When using a colour calibrated and fairly accurate NEC EA244UHD display the difference in the exported PDF colours is very different
The original bug was reported under the second scenario.
I'm not sure what this means?
It could mean the incorrect profile is being applied to the images on export which is disguised by a display with low colour range (sRGB) but is magnified by a display with a fuller gamut (AdobeRGB)?
In any case, MS Office seems to handle this correctly but there are 2 issues with LO and LO61-dev
* display in editor view is paler than actual PNG
* export PDFS have oversaturated colours
I hope this helps identify the issue.
As information I'd like to request a short description of what the current state of LO and colour profiles actually is, bugs aside.

screen print pdf's from three versions and docx in Libre - on Ubuntu
Screenprint on Ubuntu
From top left, then clockwise:
PDF from LibreOffice 3304
PDF from LibreOffice daily2080409
PDF from Word
docx opened in LibreOffice daily
To be honest, I do not see much difference.
But the same (for me) applies to attachment 141165 [details].
I set this to NEW incorrectly...
Some work has been done to the PDF export recently...
Could you please try to reproduce it with a master build from http://dev-builds.libreoffice.org/daily/master/ ?
You can install it alongside the standard version.
I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the master build
Thanks Xisco - the problem is still here.
Attached is a screenshot comparing the PDF exports from MS Word (latest), LibreOffice 126.96.36.199 and the latest daily build downloaded 31May 2018 as per your link.
The colour in the MS Word exported PDF is correct. Both the LibreOffice exported PDFs have incorrect colour.

I can confirm this.
The image is not rendered with the same colors if I export as PDF.
If I choose print and save as PDF using the in-built macOS system, it is the same color though.
Aside, if I do the test on Word I have the exact same behavior. The Word save as PDF produces an oversaturated image as well.
However, if I open the png image in Preview, make a Pages document with the image, open the LO odt with the image, open the LO print pdf export, take a screenshot, compare using the color picker in GIMP then LO and the print export does not render the same colors as Preview and Pages
Given Apple's history with color profiles I would trust them to have this correct.
Does LO have support for color profiles? Looks to be rendered in same colors on LO 3.3

This is still present
I am also wondering if this is independent of PDF export, because the image in the docx in attachment #2 is rendered with wrong colors inside LO (verified with Gimp)
