Change color of active field in MS Access form

I use a MS Access Database to do intake with new clients in real time. Lately, I have begun using a newer, faster computer. I love it, but its screen is smaller, and my tired old eyes sometimes have trouble spotting where the cursor is in the form. Various forms on the field have background colors that have significance to me concerning the gender of each person and how I will use the information in the field. None of the fields has a background color of white. I have attached three jpegs showing the form in its entirety, I would like to change the form so that the active field and only the active field - the one which has the focus at the moment, has a background color of white. This will let me know at a glance which field is active and where I will be inputting data. Then, when the focus changes to another field, I would like for that original field to return to its previous background color. It is not critical to me that checkboxes like “Hide on Website?” and “Force On” change colors in this way. I need confidence that your changes will work on my live database, so I will ask you to make your changes to my “live” database file. This has two ramifications: (1) I need you to do your work, once you begin it, within 24 hours or so on a schedule you and I set together before you begin; and (2) you will have full access to all my confidential data, so I will require you to sign the standard Freelancer NDA before our work begins.
