The hex color #284BB3, a shade of Cerulean Blue, presents some accessibility challenges, especially for text-based content. Its relatively low luminance contrast against a white background may not meet WCAG (Web Content Accessibility Guidelines) AA standards for normal text (4.5:1 contrast ratio). Therefore, when using #284BB3 for text, it's crucial to pair it with a light color to ensure readability for users with visual impairments. Alternatively, for background usage, consider using darker text.
