What is the name of the color used in CambridgeUS?

Question

What is the name of the reddish color used in LaTeX beamer CambridgeUS theme?

I would like to use this color in my table using \cellcolor command in colortbl package.

Answer 1

From CTAN you can find the source of CambridgeUS beamer theme, where there is:

\usecolortheme{beaver}

In the same site of the source you can find the beamer color theme beaver, where there is:

\definecolor{darkred}{rgb}{0.8,0,0}

I think that's what are you looking for.

Answer 2

You can determine a color in a tex document (or, for that matter, a pdf or any kind of document) more generally, and use it in your own document by doing the following:

• Have a "color picker"
  • On a KDE environment, use KColorChooser for instance,
  • On a Mac, you can use an embedded application, called DigitalColor Meter,
  • And there are plenty of open-sources softwares for every platform.
• Use it to get the html code (for instance, #A30000),
• load xcolor in your preamble,
• define your color using \definecolor{myColor}{HTML}{A30000}, cf. this post.
