The color #153A4D, also known as Nile Blue, presents some accessibility challenges. Its low luminance value of approximately 0.037 means it offers poor contrast against a white background, failing WCAG's AA and AAA standards for normal text. To ensure readability and usability, it's crucial to pair this color with significantly lighter hues. White or very light shades of gray would be more suitable for text labels or foreground elements. For larger text elements or UI components, a slightly darker background might suffice, but careful consideration is still necessary. Using contrast checking tools is highly recommended to verify compliance with accessibility guidelines and to provide an inclusive experience for users with visual impairments. Thoughtful application of this color will prevent difficulties in content consumption and interaction for diverse users.
