I want to have latex automatically add line breaks to long sequences of characters that do not contain spaces. For instance:
...................................................................................................................................................................................
into
...................................
...................................
...................................
...................................
...................................
.....
I also need to be able to manipulate the color of some of the periods using \textcolor{red}{.}, for instance. I am aware of the seqsplit package but can't seem to change fonts, sizes, colors of the text within it.

\documentclass{...}on the begin and\end{document}on the end, which will demonstrate your problem. In normal circumstance LaTeX break lines to the specified text width. – Zarko Mar 06 '17 at 01:56\parboxor theminipageenvironment? These are covered in introductory materials. Or, does your reference to theseqsplitpackage mean those dots are all characters of one long 'word'? I think more information is needed at this point.... – jon Mar 06 '17 at 04:01
