Can you change to twistie to a different color or size when categorizing

I never had this request before but I thought it was interesting. I have a form we created with 10 or 12 sections. Each section has 10-30 different fields for different types of processing. We collapse the section when first dislayed. they click on the twistie and the section expands. Is there a way to make the twisite a different color based on coding, I don’t just want to change the color. I want to change it based on a certain value of a field.

Thanks in advance for any help provided…
