You just want to change the color?

use:

strbuf.toString().replaceAll("navy", "red");

Btw.: If you really want to replace values in CSS it would be better to insert some kind of markes into the source CSS like color:${color-to-be-replaced} and replace that markers because it is more portable and reliable. Think about what will happen if you change the color of source CSS to green and forget to change the replacement code.

I Guess you are using a StringBuffer.

strbuf = new StringBuffer(strbuf.toString().replace(
  "#cit \\{font-size:16pt; color:navy; text-align:center; font-weight:bold;\\}"), 
  "#cit \\{font-size:16pt; color:red; text-align:center; font-weight:bold;\\}"));

Because:

toString() will create a copy of the StringBuffer. If you replace text in the copy, this will not change strbuf!

Whereat \\ is used to mask { and } as an not-regexp.

You cant do string replace by doing this.

mystring.replace("string1", "string2");

Instead you should do 

mytring = mystring.replace("string1", "string2");

This is because String is immutable object in java. str.replace wont affect the original str object but instead method returns a new string object.

Just do:

myString = myString.replaceAll("navy", "red");

I would use String.replace() to avoid having to deal with regexes in replaceAll()

String result = text.replace("#cit {font-size:16pt; color:navy; text-align:center; font-weight:bold;}",
              "#cit {font-size:16pt; color:red; text-align:center; font-weight:bold;}");

What about

 str.replaceAll(str,"#cit {font-size:16pt; color:red; text-align:center; font-weight:bold;}")

change

strbuf.toString().replaceAll(Pattern.quote("#cit {font-size:16pt; color:navy; text-align:center; font-weight:bold;}"), "#cit {font-size:16pt; color:red; text-align:center; font-weight:bold;}");

to

strbuf.toString().replaceAll("#cit {font-size:16pt; color:navy; text-align:center; font-weight:bold;}", "#cit {font-size:16pt; color:red; text-align:center; font-weight:bold;}");
