Flatty Yellow

Use Flatty Yellow exclusively as a high-impact accent color for elements that require immediate user focus, such as primary call-to-action buttons or alert notifications. Because of its extreme brightness, it performs best when paired with charcoal or deep navy text to maintain necessary readability levels.

Flatty Yellow is too bright and lacks the luminance contrast required to serve as a background for standard white or light gray text. It is highly effective only when used as a background for bold, heavy black typography, which ensures the text remains legible despite the intense, high-saturation yellow.
