What color code is it in \textcolor? How can I get the same color as text?

Question

What color is this? I tried \textcolor{orange}{text} but it gives slightly lighter color. How can I get similar color as the above image text provably efficient exploration and function approximation?

Answer 1

Using a color picking tool of your choice you can obtain the RGB values corresponding to the text color. Using xcolor you can then define this color with the previously obtained RGB values and use it later on:

\documentclass{article}
\usepackage{xcolor}
\definecolor{myorange}{RGB}{221,110,78}

\begin{document}

text \textcolor{myorange}{orange text} text

\end{document}
