\renewcommand is itself a command which has two required arguments, the
first being the name of the command to create or replace, and the second
being the text of the command. These arguments are supplied within
curly braces.
Therefore, "\*" is the command being replaced and "{\color{red}*}" is
what \* will generate.
If you don't put the extra set of curly braces, i.e.
\renewcommand{\*}{\color{red}*}
then \* would generate "\color{red}*" which would turn everything after
it (until the next \color command) red.
