[Tex/LaTex] Bibliography: change author color

biblatexbibtexcolor

I'm writing because I wasn't able to find a solution nor in Google nor here. My question is similar to this one, but that hasn't a solution yet. Is similar to this one too, but it uses beamer and I'm not.

My question is: how can I change the color of the author (only the author) item in my bibliography, which is formatted as follows:

\usepackage[backend=bibtex,style=authoryear,natbib=true,dashed=false,language=italian]{biblatex}

This works fine, but in the Bibliography at the end of the document, I would have the author colored. I mean, only the author, nothing more in the document, which should remain the same.

I tried by adding \textcolor to the item in the bibliography file:

@article{addicott2006networks,
 title={Networks, organizational learning and knowledge management: NHS cancer networks},
 author={\textcolor{red}{Addicott, Rachael} and McGivern, Gerry and Ferlie, Ewan},
 journal={Public Money and Management},
 volume={26},
 number={2},
 pages={87--94},
 year={2006},
 publisher={Taylor & Francis},
 langid={italian},
 }

The result was perfect for the bibliography, but it modifies also the color of the reference in the text, as in the following images:

Does anyone know how to just color the author in the bibliography and leave unaltered in the text?

(I know I'm not providing any MWE, honestly I don't think is necessary in this case. But if needed I will post it.)

Thank you for your time,
R.

UPDATE: sorry guys, here the MWE for what I'm trying to figure out:

\documentclass[12pt]{article}
\usepackage{color}
\usepackage[backend=bibtex,style=authoryear,natbib=true,dashed=false,language=italian]{biblatex} 
\addbibresource{biblio.bib}

\begin{document}

Reference I don't want to be coloured \citep{addicott2006networks}

\printbibliography[title={Bibliografia}]

\end{document}

 @article{addicott2006networks,
 title={Networks, organizational learning and knowledge management: NHS cancer networks},
 author={\textcolor{red}{Addicott, Rachael} and McGivern, Gerry and Ferlie, Ewan},
 journal={Public Money and Management},
 volume={26},
 number={2},
 pages={87--94},
 year={2006},
 publisher={Taylor \& Francis},
 langid={italian},
 }

Assuming you want 'Last, First' names where the comma within the name is to be coloured yet the delimiter between names (either a comma or 'and') is not to be coloured, use

\documentclass{article}
\usepackage{xcolor}
\usepackage[backend=bibtex,style=authoryear,natbib=true,dashed=false,language=italian]{biblatex}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{addicott2006networks,
  title={Networks, organizational learning and knowledge management: NHS cancer networks},
  author={Addicott, Rachael and McGivern, Gerry and Ferlie, Ewan},
  journal={Public Money and Management},
  volume={26},
  number={2},
  pages={87-94},
  year={2006},
  langid={italian},
}
\end{filecontents}
\addbibresource{\jobname.bib}

\DeclareNameFormat{colour-family-given}{%
  \ifgiveninits
    {\usebibmacro{name:colour:family-given}
      {\namepartfamily}
      {\namepartgiveni}
      {\namepartprefix}
      {\namepartsuffix}}
    {\usebibmacro{name:colour:family-given}
      {\namepartfamily}
      {\namepartgiven}
      {\namepartprefix}
      {\namepartsuffix}}%
  \usebibmacro{name:andothers}}

\newbibmacro*{name:colour:family-given}[4]{%
  \ifuseprefix
    {\usebibmacro{name:delim}{#3#1}%
     \usebibmacro{name:hook}{#3#1}%
     \textcolor{red}{%
       \ifdefvoid{#3}{}{%
         \ifcapital
           {\mkbibnameprefix{\MakeCapital{#3}}\isdot}
           {\mkbibnameprefix{#3}\isdot}%
         \ifprefchar{}{\bibnamedelimc}}%
       \mkbibnamefamily{#1}\isdot 
       \ifdefvoid{#4}{}{\bibnamedelimd\mkbibnamesuffix{#4}\isdot}%
       \ifdefvoid{#2}{}{\revsdnamepunct\bibnamedelimd\mkbibnamegiven{#2}\isdot}}}
    {\usebibmacro{name:delim}{#1}%
     \usebibmacro{name:hook}{#1}%
     \textcolor{red}{%
       \mkbibnamefamily{#1}\isdot
       \ifdefvoid{#4}{}{\bibnamedelimd\mkbibnamesuffix{#4}\isdot}%
       \ifboolexpe{%
         test {\ifdefvoid{#2}}
         and
         test {\ifdefvoid{#3}}}
         {}
         {\revsdnamepunct}%  
       \ifdefvoid{#2}{}{\bibnamedelimd\mkbibnamegiven{#2}\isdot}%
       \ifdefvoid{#3}{}{\bibnamedelimd\mkbibnameprefix{#3}\isdot}}}}

\DeclareNameAlias{sortname}{colour-family-given}

\pagestyle{empty}
\begin{document} 
\autocite{addicott2006networks}
\printbibliography
\end{document}

sortname is the name format used in author-year/author-title-like styles for the labelname.
