Adobe RGB is not suitable for web posts, this shows why.

Why Adobe RGB should not be used for web posts

For those that would really like to get stuck into this they can read HERE.
However I have created a quick demo, not as good as the ones on the linked site, which shows what happens with an image in Adobe RGB which is then viewed in a colourblind browser or on an iPad/tablet. There are still quite a large number of colourblind browsers in use and the iPad/tablet is not normally colour managed.
So the attached image shows a matrix view of the colorchecker when colour managed and when not colour managed. The saturated colours are where the Adobe RGB embedded profile has been correctly read by the Software/Browser/Operating System and the de-saturated colours are where the embedded profile has been ignored as it would be by colour blind software/Browser/OS. The web is almost exclusively sRGB and therefore posting with any other embedded profile sRGB means that some viewers will not see the colours intended. Discussing colours then becomes a bit fruitless! :-)
