Change form field text- can’t read

I need help changing the color of some of the text on my form?

Why isn’t there a simple, light/dark theme option?

This is what I have so far from reading through the forum:

form[id*=give-form], form[id*=give-form] legend {
color: white;
}

form[id*=give-form], form[id*=give-form] legend, form[id*=give-form] p {
color: white;
}

form[id*=give-form] span.give-final-total-amount {
color: red;
}

body.give-twentysixteen .give-btn, body.give-twentysixteen .give-submit {
background-color:green;
}
.entry-content #give-recurring-form, .entry-content form.give-form, .entry-content form[id*=give-form] {
color:white;
}
form[id*=give-form] .give-donation-amount .give-currency-symbol {
color:#333;
}

It has fixed “Select Oayment Method” and “Person Info” but as you can see I cannpt see the currency symbol, “PayPal” r Donation Total.

Also, once Name and Email are entered, they are dark and difficult to read.

Anyway here is a screen shot of my issue.
