Create custom cite by comparing citeauthor in if statement

Question

I'm trying to recreate the \cite behaviour for multiple authors using a custom citing format. Essentially I want to have the author's name in black text, while the year is a colored hyperlink. Would anyone know how to accomplish this?

My current attempt is to recursively build the citation by feeding in the last author (#1 in addcite) and the remaining list of works to be cited (#2,#3). The first work to be cited is popped off from the remaining list (\citeauthor{#2}) and compared to the reported last author (#1), then the behavior is decided based on if it is the same author or not. However, I cannot get the comparison to work (I think it has to do with the comparison not comparing the literal text, but maybe differing because they have different hyperrefs, being the same author but different works). And for some reason the first work is always lost (but works fine when given a single citation).

\newcommand{\mycite}[1]{(\addcite(,#1,))}
\def\addcite(#1,#2,#3){%
\def\temp{\citeauthor{#2}}%
\ifx\temp#1%
\citeyear{#2}%
\else{\hypersetup{citecolor=black}\citeauthor{#2}}~\citeyear{#2}%
\fi%
\def\tempA{\citeauthor{#2}}%
\ifx\relax#3%
\relax%
\else; \addcite(\tempA,#3)%
\fi
}

Ideal working solution would take

\mycite{AuthorA_Year1,AuthorA_Year2,AuthorB_Year1,AuthorB_Year3}

and return (punctuation not important):

AuthorA (Year1; Year2); AuthorB (Year1; Year3)

Where AuthorA and AuthorB are in black, and the years are in whatever the citecolor is defined as from hyperref.
