That should be valid, but only if the texture is like the following example.
#declare ColorMappedTexture=
texture {
pigment {
granite
color_map {
[0 color rgb <1,0.3,0.1> ]
[1/3 color rgb <0.7,0.5,0.3> ]
[2/3 color rgb <1,0.7,0.5> ]
[1 color rgb <0.5,0.3,0.1> ]
}
}
/* a finish statement could also be here and can be overriden later */
}
texture {
ColorMappedTexture
finish {specular 0.5 roughness 0.01}
}

If you are still referring to the 'cannot layer over patterned texture'
limitation and your inability to add a finish to change ambient, diffuse,
specular, etc. I think you should be okay until trying to add yet another
texture statement. For example:
texture {
PreviouslyDeclaredLayeredTexture
texture {AnotherHere} // error
}
whereas the next example is okay:
texture {
PreviouslyDeclaredLayeredTexture
pigment {AnyColorMap} // no error
finish {AnyFinish} // also no error
}
This being POV-Ray version 3.5 I am using here, not sure about the previous
versions.

My guess is that you are getting textures added into textures, and therein
lies the problem.

Patterned textures don't interact well with layering. It's certainly an
undesirable "feature", but is too much work to fix. It would be easier
to rewrite the code...and as such a rewrite is already planned for 4.0,
there isn't much incentive to do such major work on 3.5.

The answer to this question is to increase ambient in the finish...but I
think you're asking the wrong question, because this doesn't have
anything to do with patterned textures.

You need to explain what you're doing more clearly. You are working on
some kind of GUI editor that lets you do things like lighten an existing
texture? You need to say exactly what you're trying to do and exactly
what you're doing.

OH! then thats why! -The eks that Bob H. shows does work properly.
(Thanks Bob!!)

Its a 'summer' project -a delphi app that let u define primitives and select
predefined textures (or create and save one) then a pov file is generated
i do not have a lot -spheres and boxes dimensions w. positions and textures
and then the grief came :)
Thank you to both of you!
