Text can be colored:
\documentclass{standalone}
\usepackage{xcolor}
\begin{document}
{\textcolor{green}{\Large I}}
\end{document}
Areas can be filled with patterns
:
\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{patterns}
\begin{document}
\begin{tikzpicture}
\draw[pattern=bricks, pattern color=green] (0,0) -- (0,1) -- (1,1) -- (1,0) -- cycle;
\end{tikzpicture}
\end{document}
How could you fill letters or symbols with a pattern
?
For example, an "I" filled with green bricks would look something like this:
\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{patterns}
\begin{document}
\begin{tikzpicture}
% shouldn't need to trace a symbol!
\draw[pattern=bricks, pattern color=green] (0,0) -- (3,0) -- (3,1) -- (2,1) -- (2,3) -- (3,3) -- (3,4) -- (0, 4) -- (0,3) -- (1,3) -- (1,1) -- (0,1) -- cycle;
\end{tikzpicture}
\end{document}
