Colour and links

Adding colour

• The xcolor package lets you colour text. Load it, then wrap words:

\usepackage{xcolor}
...
\textcolor{red}{This is red} and \textcolor{blue}{this is blue}.

• Built-in names include red, blue, green, orange, gray, and more.

Highlights and your own colours

• \colorbox{yellow}{text} puts a highlight behind the words.
• You can even mix your own: \textcolor{red!60}{...} is 60% red (lighter).

Clickable links

• The hyperref package turns cross-references and web addresses into clickable links:

\usepackage{hyperref}
...
Visit \href{https://ctan.org}{CTAN} for packages.

• Load hyperref last in your preamble — it likes to have the final word.
