How do I change the background of a dropdown?

I would like to change the drop down menu color from the redish brown it currently is to RBG #ACACAC. I cannot seem to find where I can change it. This form was originally copied from a Jotform template and I am thinking there is some properties that were inherited from it that I cannot see or change. 

Thanks!

In order to apply the change you have in mind, please inject this custom CSS code into your form:

#input_11>option {

    background-color : #acacac;

}

I can see that you are already familiar with how to inject custom CSS code into the form, but for completeness here is our guide: https://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes

I have also created a corrected form in case you would like to examine it or clone it: https://form.jotformpro.com/71595861568977

I hope this helps. If you need further assistance please let us know. Thank you.
