The color #1B4257, also known as Blue Dianne, presents some accessibility challenges, especially when used as text on a white background. Its relatively low lightness value (around 15%) means that the contrast ratio might fall below the WCAG recommended levels for normal text (4.5:1) and large text (3:1). To ensure readability, consider using a lighter color for the text if #1B4257 is used as the background, or conversely, use a darker color for the background if #1B4257 is used as the text color. Testing the color combination with accessibility tools is crucial to confirm compliance with accessibility standards. When used for interactive elements, such as buttons or links, ensure sufficient visual cues are provided in addition to color to help users with visual impairments understand the element's purpose. Avoid relying solely on color to convey information.
