please tell me the necessary packages that I must use to get blue colored cross-referring to Fig.1 and Eq.(1). I want to change the color of Fig.1 from black to blue. Thank you very much in advance.

you only need to add the hyperref package. The setup commands also needed are:

\usepackage{hyperref}
    \hypersetup{
        colorlinks   = true,
        citecolor    = blue
    }

  • If I use this code, I get the blue colored number when I cross-refer the Figures and Tables but the word Fig. and Table. is still in black color. Thank you – Prakash Dec 17 '17 at 10:33
  • Hi, @Prakash try using \autoref{} instead of \ref{}. So you do not need to put Fig. or Table. – LambertG Dec 18 '17 at 14:08
