Change color of text as you type

[dmontano]

I have a field configured with field validation - set to a maximum of 55 characters. I would like to display some visual feedback to the person entering data when they have exceeded this limit.

Since the validation occurs after the field is exited, it's not very smooth throwing an error dialogue after they have typed beyond the limit. I am unable to provide visual feedback while they type. It would be helpful to display the text in black as the type while under the limit, and maybe display the overset portion in red text. 

Any techniques for this?

Disregard this - I figured it out with a global field and a script trigger.
