How to add custom colors in LaTeX?

  • 772

When writing documents in LaTeX (specifically, I use LyX for it), I'd like to use some custom color for the text; for example, instead of using \textcolor{red}{abc}(red RGB(255,0,0), which works perfectly) I'd like to use something like \textcolor{#990000}{abc}(dark red RGB(153,0,0)this throws an error).

So my specific question is:

  • How can I define the color of the text in LaTeX?
  • Is it possible to define a custom color to use within my document?
    For example, would it be possible to define a color rojo_oscurowith value #990000and use it in my document like \textcolor{rojo_oscuro}{def}?

    You can use latexcolor to include quite a few extra predefined colors. To use it you must include it more or less like this:

    \usepackage[usenames,dvipsnames]{xcolor}

    or, as it says here , you can do just this:

    \usepackage{color}

    Then you will have to search for the colors by their name and use the one you want, the list looks something like this:

    enter image description here

    You can read more here and if you need any colors not listed, which I doubt since there are almost 1,000 colors, you can make one pull request here .

    You can also define a custom color in RGBlike so:

    \definecolor{rojo_oscuro}{RGB}{153,0,0}

    or use the codeHTML

    \definecolor{rojo_oscuro}{HTML}{990000}

  2. From the package xcoloryou can use \definecolor. For example:

    \usepackage{xcolor}
\definecolor{rojo_oscuro}{RGB}{153,0,0}

\begin{document}
\textcolor{rojo_oscuro}{Hola mundo}
\end{document}

    If you prefer to specify the hex value of the color (HTML):

    \definecolor{rojo_oscuro}{HTML}{990000}
