Suddenly I wondered, why is black the default pigment? Wouldn't white
make more sense?
.. and also suddenly I realize somebody will see this wondering as racism :)
Anyway, off to POV-Raying again.
cu!

Because black is the lack of any color, which makes sense as a default.
(Also, if you think about it in term of numbers, zero makes sense as a
default.)

I guess so, but still, one would expect the default texture to be
usefull, no? I mean, if I'm just modelling stuff, without yet worrying
about the texturing, I use a simple white pigment.
It's of course a minor job to create my own default texture, but I
wonder if anyone (except maybe in a "short code contest") ever uses the
current, black, default texture. And if noone does, doesn't that mean
that noone really agrees with black being the right choice for a default
texture?
Oh, well, doesn't really matter actually, it was just some random
wondering :)

Put
#default { pigment { rgb 1 } }
at the beginning of your scenes, and you'll have what you want.

I know that, and that's what I do. My question wasn't how to do that,
but why I should do that.
Or rather: why the default texture is actually unusable in 99% of the
cases, whereas it would be very useful for almost any test rendering if
the default pigment was white.

Personally I think red is a good default colour. It shows where I have
forgotten to texture an object. I suppose rgb <1,0,0.5> would be better
for that.

There. That's the reason why it is like it is: There are multiple
pigments that would make sense. But of all conceivable colors, there is
one that is special - the one and only which preserves backward
compatibility: Good old pitch black.

The problem here, is that ANY default pigment would be
unusable/useless/anoying for many peoples.
In my case: There are cases when white is a good choice, other when pure
red or green are more usefull, and usualy, pure black is perfect.
That olds true for the default pigment, finish and background.
Even for the same person, a default can be optimum in one case and next
to unusable in another.
So, that's why there is a #default{...} directive and several background
features.
