Colour Management in your web browser - Test Images
This page contains a number of test images saved with different icc profiles and settings. As you will see, most browsers take no notice of colour settings or profiles. Not for nothing is colour mangement on the web known as 'Colour Manglement'

Keith has written an article covering this and many more aspects of using photos on the web. The example image (©Photodisc Inc.) is the PDI freeware test image (license details-PDF) The What's New Page gives a quick overview of the hundreds of pages of articles and picture on this site. This page is part of the Articles section of our Info and Resources feature Northlight Images prides itself on its independence when giving advice.

There is a link to all the various colour management information on this site at the end of this page.
The first examples show the result of saving a file with its correct profile. In this case the files were converted in Photoshop and saved as jpegs with the 'embed color profile' option ticked.

Saved in sRGB

Saved in ColorMatch RGB with ICC profile
If colour mangement is working in your browser then all three images should look the same
The two examples below show what happens if you do not attach the profiles

The examples below show what happens when you take a file in Adobe98 and just assign a profile to it. One has the (wrong) sRGB profile attached, while the other does not.

| Adobe98 file
Assigned a sRGB profile |

Assigned sRGB, but saved w/o profile |
Safari (1.2 and above) and IE5 on the Mac seem to get it right. I'm not aware of any PC browsers that do, but please do let me know if you are using one that works (all three images in the first set should look the same)
There is also the problem of how untagged images are handled, which also seems pretty much a random choice of the browser writers.
And if you are someone who uses a big space like ProPhoto, be very careful with images that end up on the web.

Note the distinct hue shift in the man's shirt - this would happen to nice blue skies.
