This is an interesting point, but seems to be more complex :-)
But we can offer that as an further output, so users can decide what to 
use themself.

As a starting point it would be perfect if 
http://dbpedia.org/resource/Edinburgh is being colored the same way in 
different tools.
Maybe this could lead to a more frequent re-usage of URIs. A further 
advantage is that it can be reimplemented without using any web service.

A second step could then be if http://dbpedia.org/resource/Edinburgh and 
all the other 120 listed resources about the same thing are coloured the 
same.
The usability of tools would be heavily improved but needs a further 
pre-processing step.

We can offer that approach as well. and integrate respective code 
snippets on our snippets page ( 
http://cold.aksw.org/index.php?page=snippets).
I will add sameAs.org on our tools ( 
http://cold.aksw.org/index.php?page=tools) page? Is that ok for you? :-)

ok, there is a 24bit limitation but i would like that idea as well :-)
