Hi all!
This is my very first post ever :))

I am still a beginner so mabe this post might be somewere else. If that is
the case, my apologies to all.
Well, I was experimenting with PovRay 3.5 beta 7 and I was trying to get the
"negative" of a color when I get some unexpected results (at lest to me :D).

My question is: Is   rgb 1    the same as   rgb <1,1,1> ?

pigment{color rgb 1} gives the same result as pigment{ color rgb <1,1,1>}
but
pigment{color rgb <1,1,1> - Gray25} gives the expected results and
pigment{color rgb 1 - Gray25}results in something completely different.

I've tried this in PovRay 3.1g and the result is the same (also an
unexpected result).
Both versions show a warning message while parsing: Suspicious expression
after rgb. (If someone could explain in what situations this appears I would
be grateful)

Well, my question is: What is the difference between rgb 1 and rgb <1,1,1>?

I've encolsed 2 pics to show what I mean.

Thank you.

PS: sorry for the English (I an Portuguese)

Em primeiro lugar, Benvindo :-)

Now that you posted your files with a sensible size, perhaps it would be a
good idea to cancel the large post, so people don't download it by mistake
(like I just did).

Anyway, good to know our portuguese speaking community is increasing. Please
drop by the povray.international forum sometime.
