A text field that you've inserted? Why not just format the color when inserting it?
Perhaps you mean a string type of field, a text field is a type of field within Crystal for typing text or inserting fields into.
You might accomplish this by parsing out the string into words before the word, the word, and then after the word, or you might use HTML formatting in some way as well.
Could even be that you could use a SQL Expression and embed HTML formatting within the field using a replace function.
Things like the version of your software and whether this is a typed text field or you mean a database field or a formula, etc., would be useful to know so that we don't waste time.
