Latex \hyperref not changing the color of citations

Question

This question is based on this stack overflow question. According to the answer given,

\hypersetup{
  colorlinks,
  citecolor=Violet,
  linkcolor=Red,
  urlcolor=Blue}

it is possible to change the color of citations. However, when I do that, I am not getting any color. Everything is looking black. I tried many permutations to the answer like colorlinks=true, colorlinks=false, removing the field colorlinks altogether, but every time, I am getting the same black color.

Am I to add the package xcolor in order to work this? Can anyone help me.

I am using org-mode to write the document and exporting to PDF using org-latex-export.

You don't show any useable code, but if I were to guess, I'd say you did not define the non-standard colour names with capital letters. Either define them or use standard names from one of the color packages, e.g. from xcolor

\documentclass{article}

\usepackage{xcolor}
\usepackage{hyperref}

\hypersetup{
  colorlinks,
  citecolor=violet,
  linkcolor=red,
  urlcolor=blue}


\begin{document}


\url{URL}

\end{document}
