On the mailpoet settings tab where you work with subscribe forms, you’ll see a link to get an HTML version of the form instead. Use that link, then insert the code into a WordPress Text/HTML widget to create the form. You can then add a style attribute to each form element to get the text color you want, i.e.:
style=”color: #000000″ //black text
You can do this for the button as well to change it’s text color. BE WARNED: the HTML code contains a bug you’ll need to deal with, I’ve just posted about it here: https://ww.wp.xz.cn/support/topic/bug-header-scripts-for-html-version-of-subscribe-widget-breaks-page/
Good luck!
