Thank you again, Stefan!
Yes, I solved the problem of extracting the exact color codes using
substring-before and substring-after, so this is not a problem.
I will try to explain again.
The default template for <phrase> creates
<span class="phrase">some text</span>
in HTML output.
If we specify the role "color:red;" for a <phrase>, then by default the
following output will be created:
<span class="color:red;">some text</span>
I should probably avoid creating a new class by specifying
phrase.propagates.style=0. Then even with role="color:red;" the output will
look like
<span class="phrase">some text</span>
I can extract this "red" from the role's value, and I don't care about the
class name (because I'm not going to define a new style in CSS).
But the question is, how to add a *style* to the <span> using stylesheet
customization at all?

Hi Ekaterina,
as far as I understood your original mail, you managed to get your list of
values parsed in the case of XSL-FO.
If not, you will have to write some XSLT to parse your pseudo-CSS...
Expect this to be a bit hard -- XSLT (at least, 1.0) is not really made for
string manipulation, and adding some error tolerance may bloat your code even
more.
Presumably, that parser would be based on first looking for a ";" , splitting
that string off, then looking where the ":" within your split-off string is.
And then you would continue...
If you are looking for inspiration, in your local DocBook stylesheets
installation, take a look at lib/lib.xsl, and specifically the template
"pi-attribute". This template solves a similar issue, trying to figure out
constructs like 'attribute="value"'.
You can also take a look at my horrible old code to parse things like
'attribute = value;' [1].
You would then have to add in a list of attributes to allow and a list of color
names to allow. And then match against those.
Hth,
Stefan.
