How to change the text color of the richtext box in infopath

[sathishm]

Hi,

I have added a rich text box to my infopath form which is created through
vs2005. I want to change the text color based on the user. If User1 inputs,
his color would be blue. Then user2 will be allowed to edit that text. When
user2 comes the text entered by user1 should be displayed in blue and the
text edited by user2 should be in RED or any color which is assigned. How
could i set the property.

Thanks in advance
