Fluent Forms - Styling Issues

Hello, I am having issues correctly styling forms with fluent forms, I am trying to make the radial fields orange when checked, its working on computer, but on mobile its not applying it on the border and is staying blue...

What am I doing wrong, Iv used css to make the option text white Form.fluent_form_3 .ff-el-form-check label.ff-el-form-check-label {
color: #ffffff;
