Create a modified cite command that colors the number inside the square brackets

by Henry   Last Updated May 16, 2019 02:23 AM

i was searching for the past hour and couldnt find an answer. I'm using the cite{} command and its working nicely ofc. But I would like to make a small modification. When my reference appears in the text, the reference number inside the square brackets should have a specified color. How can I achive this (please see attached picture below)? Only the inner number should be colored and the outer brackets should stay black. Any help is appreciated, thank you very much.
