Did anybody even bother to check ou the link I posted on page one? It explains the why of it. He provides some test images with tabs showing the effects of different color spaces. Most monitors cannot display al the colors (gamut) of Adobe RGB. Some cannot even cover all of sRGB. And depending on which browser you use, your browser might display different colors than what are "true", which is why it is important to embed a color profile in the metadata.

It's a long read. The material is over 13 years old and it's not really easy to follow.

Some of the points being made may be very out of date or obvious. For example, if an image has an embedded profile but it is ignored the colors won't look right. Is this really news to anyone? On the other hand, if the embedded profile is recognized and the monitor is calibrated it will probably look right. Anyone surprised there?

It really does not address the need for one particular color space over another.

A more useful set of examples might be images that display correctly in one profile when the profile is appropriately embedded and recognized vs. incorrectly when saved in another profile with that profile appropriately embedded and recognized.

Yes I did. It has some problems. It's dated. It's so dated that what it claims is the case may now be the opposite. For example: "And herein lies the problem: many browsers are not “color managed” applications, meaning that they do not know how to recognize or understand color profiles." I believe today that would best be said as; most if not all browsers are color managed and do correctly interpret image color space profiles. That article is 13 years old -- in this business that's a long time.

It has embedded links that not surprisingly go nowhere.

It's got some technical weaknesses and misunderstandings. Referring to sRGB for example the article claims: "It's the official default color space for the World Wide Web." No it is not. It's appropriate to say that sRGB is the best choice color space to use when placing images on the Internet, but the Internet has no color space let alone an official one.
