Hi!
Sorry!
For creation and a coloring of this curve I used while
I want to learn, whether it is possible to paint so sphere_sweep? I can't.
Povray doesn't want to create 4000 curves using while: it is a big problem at
creation of hair. :(
Thanks!

One rule of povray: the pattern/color is 3D distributed, the shape is
just immersed in the pattern.
(forget about UV-mapping)

Let me try; the sphere_sweep is not UV mapped, it only displays patterns that
are distributed across it through 3D world space. That means a gradient won't
work like it would on a UV map.
You could normalize the texture distribution on the sweep first, over a certain
axis, then transform it into position to maintain those colors...

Could also save UV mapped parametric mesh representations of the sweeps and
render those just as one normally would expect the hair to be textured.

If I understand you want to create more than 4000 curves using while and
sphere_sweep?

That's right. It's just like that object intersect the pattern.

Interesting, but I am lost about your two solutions ;-) would you mind
to give us a little piece of code?

This image contains 5000 curves made with sphere_sweep and a while loop.
It is that you want?

Hair in a blender are presented by the array from splines.
Developers of the official version of the Blender2Povray exporter used these
splines for sphere_sweeps array creation.
Povray counts sphere_sweep enough, but,
I had an idea to streak hair, to decolour tips of hair as it is done by some
people in beauty shops or hairdressing salons.
I tried to paint sphere_sweep as necessary.
At me it didn't turn out.
Therefore I addressed to other way to use the array of splines of the Blender:
while
But, I can't use the second way to receive all hair: the system hangs.
Therefore here I asked a question of opportunity correctly to paint sphere_sweep
From all comments I understood that such opportunity isn't present.
I can't make transformation of hair after texturing
Maximum of hair by means of while
