Hi there @Eddy1994, 

Welcome to the Community! Happy to help!

Recently, Klaviyo has launched new features to ensure that campaigns and forms are more accessible to all who might encounter them and be ADA complaint. You are seeing this issue it’s low contrast can be an accessibility issue for some. Creating visuals with higher contrast in colors between font and background color and form & background color would be more aligned with accessibility principles if you would like for your form to meet WCGA standards. These alerts display in case there are any potential issues to make you aware of to show you exactly what's going on, how to fix each alert, and will allow you to dismiss them as well, however, they will not prevent you from publishing your form. 

For more accessibility best practices in emails and forms, you can check out our help center documentation here. 

Thanks for participating in the Community!
