I have a weid thing happening with my Bootstrap 4 form validation where with two radio buttons have their label's foreground being changed to green when the form is validated. If the form is invalid, the labels don't change to red. Either way, they should persist their black foreground because the radio button inputs do not have the required attribute associated with them like my other form elements. Why would they turn green and how may I prevent this or stop form validation from occurring on these two entities?
index.html
<form id="signup-form" novalidate>
<div class="form-group">

Result
Before form validation
After form validation

Reset to default 5When the form is validated with HTML5, the :valid state (or :invalid on validation failure) is applied to all of the form inputs. I don't know of a way to prevent the :valid state from being applied to specific inputs.
Once :valid has been applied to the input, Bootstrap has this CSS which makes the label green...
.was-validated .form-check-input:valid~.form-check-label {
color: #28a745;
}
To override the green style that Bootstrap is applying, use the text-dark class on the label. This way the label will always be black, and not green(:valid) or red(:invalid).
