Yes indeed. They render much better with the latest version of POV-Ray
or UberPOV.

You don't get my point. In practice nowadays nobody cares what the W3C
did recommend a long time ago when monitors where CRT's and smartphones
where not invented yet.
The color space of the majority of viewing devices currently used is not
even close to sRGB and with upcoming 4k displays and even HDR displays
for the consumer market they get even farer away. And as I mentioned
before, this does not make just a subtle difference.
This was also not a personal request of mine (I know about the problems
very well and can work around it if I want to), it is an advice for
everybody who cares about what others will see if they look at an image
one might have created with a lot of effort.
So what you call a bullshitty implementation is what I call a necessary
step in the right direction.

Ouch! You just ruined my day and almost my marriage as I promised my
wife to do some cleanup in the garden this morning.
Anyway, I just realized that the IC version on my webpage is 8 years old
(doesn't time fly by?) and therefor completely outdated. I just did put
up a more resent 64-bit version of IC that supports ICC profiles for
writing TIFF and JPEG files.
And BTW when I tried to maintain my website I noticed that FireFTP (the
Firefox plugin I was using for this purpose since a decade) does not
work anymore as Mozilla has changed its plugin policy and so had to
spend hours to find some replacement that at least works somehow in the
way I like it.
This also reminded me that I wanted to change my side from http to https
... oh my, so many things to do and so less time ...

Oh, the garden can wait. IC is much more important than either marriage
or gardens, isn't it! ;-)

You misunderstood. The maintained site is already up and running and IC
1.1.7 64-bit ready to download.

I'm coming late to this conversation; sorry.
This surprising situation looks like a very big 'can of worms' that needs
further discussion, maybe in a separate newsgroup thread. It goes to the heart
of what we can expect our images to look like on other computers/monitors.

Following the comments, I re-assessed different elements, in particular
de-saturating some of the image_maps used. I also gave dynamic t-shirts
to the girls instead of the conforming ones in the original.
While re-processing through Poser, changing the facial expressions of
the girls, the flag was changed. The letter 'N' may not really be
visible any more but this version clears the head of Cathy which I find
better.
As far as I am concerned, my final version.

The expression are less solemn, but the t-shirts are really well done.
A nice version.

Thanks Paolo. I changed the expressions mainly because they were at the
limit of what Poser can do correctly. I preferred to backtrack a bit.
