How to change Contact form 7 border color?

I have created a contact form 7 form
Its default colour of boxes border is white
and my theme background colour is also white
so boxes border are not visible
now I want to change the border colour of the form items
I have changed few border colors to black but I am not able to change few border colors

This is the coding of my form
____________________________________
<label> Your Name (required)
[text* your-name] </label>

<label> Your Email (required)
[email* your-email] </label>

<label> Your Phone (required)
[tel* tel-40] </label>

<label> Services </label>
[checkbox checkbox-261 use_label_element “Social Media Marketing” “Search Engine Optimization (SEO)” “Google Ads” “Email Marketing” “Website Development”]

<label> Tell us about your project
[textarea textarea-112] </label>

<label>Project URL (Leave it blank if unavailable) </label>
[text ProjectURL]

Upload a File (optional)
[file file-609]

<label> Preferred mode of contacting you </label>
[select menu-245 “Call” “WhatsApp” “Email”]

[submit “Send”]

This is the addiontal CSS I wrote

input[type=”text”],
input[type=”email”],
input[type=”tel”],

textarea {
border-color: #000000;
}

This additional code has changed the border color to black of ‘name’ ’email’ ‘phone’ ‘tell us about your project’ and ‘project URL’ BUT border color of ‘upload a fie ‘ and ‘preferred mode of contacting you’ is still white

What additional codes do I have to write in order to change their border color to black as well?
