The user has the option to highlight fields or not, but that is user by user preference. If they choose to highlight fields they will be light blue. You can denote certain fields to be required and they will be outlined in red, with the light blue highlight.
So it sounds like you just need to make a simple change to show certain fields as required so you get the red outline.
I do have some code that I got from this or another forum that demonstrates how to highlight the current field that a form filler is working with, highlight fields that a form filler is required to fill, and use message boxes to provide feedback to a form filler. I've pasted it below.
// This script performs a series of checks to verify that any required fields
// contain data. In this case, each field is individually checked to verify
// that the value of the field is non-null or an empty string. If the value
// of the field is null or an empty string, an alert message is displayed
// indicating that data must be input into the field and the background color
// of the fillable area is changed to red.
// Use this variable to indicate if a field does not contain data.
