That's a surprise to me. I can however confirm it for the latest

versions of both Insight and Web.

That makes sense to me.

I have filed a ticket to have us look into this:
<br>
<a class="moz-txt-link-freetext" href="http://trac.openmicroscopy.org/ome/ticket/13146">http://trac.openmicroscopy.org/ome/ticket/13146</a>. It certainly
doesn't
<br>
agree with the OME-XML schema documentation I pointed you to
previously.
<br>
<br>
In the meantime, if I set the alpha channel to just 01 instead of
00, so
<br>
very nearly transparent, then both Insight and Web behave as we'd
<br>
expect. Perhaps that workaround may suffice for now?

<br>
Yes, I saw the same thing. It will work for now.<br>
<br>
Thanks for your response.<br>
