I have to submit a revised paper with several new references. Those must be highlighted in the color blue. What I want to accomplish is that only those citations are colored in blue in a \citep environment, for instance:
\citep{a, b, c}
Here I just want 'b' in the color blue. I tried with \color command, and the hyperref package, but it seems that they just effect global changes.
Is it possible to do this?
