You might be able to be more precise using ereg_replace(). But I donot know
the regular expression to make it happen. Or if your situation allows it
you can hack it by appending a single space on the end of each input.
Either way what you need to do is give the script more information about
exactly what you want to replace.
echo str_replace("Blue ", "Red ", $paragraph);
