Another utilization would be to improve the visibility of text with very light colors for better reading on a white background.

Our example will use the color yellow for chapter headings in a book. This is hardly readable, so we will add a black contour to improve the readability:

\usepackage[outline]{contour} \contourlength{1.5pt} - Define a macro for the new chapter...
