Sign-up form, CSS for checkboxes

Hi there!

I would like to know what I should do to change the font color of checkboxes (sign-up form) from default-color to white.

I have installed your plugin in my WP site and configured “Load form styles (CSS?” as “Yes, load basic form styles”. My widget is shown inside a dark footer, so I would need all the texts in light font-color. All default texts (title, label, text inside the placeholder, etc) are written in white (that is perfect), BUT texts linked to checkboxes (group created in MailChimp, and added as a new field in the widget) are shown in dark grey, so illegible in my case. Please visit my site to see the effect:

(scroll down, the mailchimp-fpr-WP widget is in the footer, on the left).

I have tried to include “color: white” inside the form mark-up (form settings in WP), and also adding some CSS code (“color: #FFF”) to file “mySitewp/content/plugins/mailchimp-for-wp/assets/css/form.css”), section “.mc4wp-form” but nothing of this is working. Maybe I’m not applying the right CSS rule in the right file/section?

I would really appreciate your help to know what I should do to alter the visual appearance of the checkboxes inside the sign-up form (if applying CSS rules to .mc4wp-form, could you please let me know which code and where (line) to be added?).

Thanks in advance and awaiting your reply.

Kind regards
