No in Windows nessuna differenza fra Firefox e Internet Explorer,
probabilmente Safari in mac usa uno spazio colore diverso da firefox, ma non chiedermi come fare a controllare
ho trovato questo:
the Safari ProblemI know that only a few webusers surf with Safari(Mac).
Safari does CMM according to ICC standard. It reads embedded profiles out of images and does accurate color transformation.
The Only Problem with safari is:
if there is no profile embedded, the Mac-CMM (ColorSync) interprets image data as if they where in the MONITORS color space.
I´d think that Safari developper don´t even know, that they are writing a colormanaged webbrowser, becaus they ignore internet standard recommendation (and Apple likes standards

) and if you coding on MacOS there is colormanagement includes automatically.
ma aspettiamo i mac-users ...
