Changing a Dynamic Text's color after using IF statment

Well here i will talk abit about changing a Dynamic Text’s color after using IF statment.

The script is this way:

if ( name_field eq “”) {
_root.status_field = " Please Type Your Name";
//here is the problem, the text should be red color,

so the text was in White color, but the message that will apear in the Status field should be red.
but what script should be used.

so any help here will be appriciated.
