Firstly, my apologies if you've come across this post on one other forum that I frequent, but I thought it worth posting here too, as I feel it may be of interest... For some time now, I've been using an X-rite ColorMunki Display colorimeter and X-rite's official software to profile the displays on my Windows 10 system, and I've been fairly happy with it. My browser of choice for the last five years or so has been Chrome, and I've updated regularly (currently at version 65). I also have Firefox (version 59), but have rarely used it... until now (read on ). When posting photos on forums, I've noticed some colour differences between what I see in Lightroom and Chrome. Not huge differences, but noticeable. Yesterday, I decided to move away from X-rite's software and replace it with the quite-highly-regarded open source DisplayCAL tool, which I already use in my Linux Mint installation with good success. The profiling worked flawlessly, and Windows Desktop and Lightroom both showed the temperature and colours I'd broadly expected. But when I loaded Chrome, the colours for websites and photos were way off base... faded / posterised / just plain weird.I checked "chrome://flags" and confirmed that "Force color profile" was set to "Default", thereby (allegedly) using the active colour profile for the current display (unfortunately, it's not possible to force the colour profile to a specific path and file). I then changed that flag to "sRGB", restarted Chrome, and everything looked pretty much OK again - though on close inspection, the accuracy of colours compared to Lightroom still wasn't quite right... reasonably close, but no cigar. Next I loaded Firefox, went to "about:config" and set "gfx.color_management.display_profile" to the path and file of my new DisplayCAL profile, and restarted. Lo and behold, photo colours were rendered exactly as I saw them in Lightroom. So, in summary: (1) Chrome has never (so far as I can tell) rendered colours 100% accurately for me - not when compared to Lightroom, and it seems it's the browser at fault. (2) Chrome is happy with X-rite-produced profiles, but doesn't like DisplayCAL XYZLUT + matrix profiles (why is that?). (3) Firefox seems to like both X-rite and DisplayCAL profiles, and is far more accurate in reproducing the colours I see in Lightroom. In the interests of a reliable colour-managed workflow from capture, through developing / editing and finally online viewing, I'll be sticking to Firefox for now. But I can't help wondering if I'm missing something, or doing something incorrectly Has anyone else run into difficulties with colour-management in Chrome? And how about the profile differences... why is it, I wonder, that Chrome doesn't like DisplayCAL profiles?
