Think about what your website would look like if you took a black and white photo of it. The best way to convey information clearly in this situation is to make sure the information stands out against the background.
You can use a contrast color checker to make sure the foreground and background colors contrast enough.
For your convenience, we provide you with a color palette that meets WCAG AA guidelines for color contrast on a white background.
