The hex color #2255c4, a shade of Cerulean Blue, presents specific accessibility considerations for web design. Its relatively low luminance value means it requires careful pairing with text and other elements. When used as a background, it necessitates light-colored text (white or very pale shades) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. Conversely, if used for text, a much darker background is crucial. Insufficient contrast can lead to visual strain and difficulty for users with visual impairments. Additionally, relying solely on color to convey information is discouraged; supplementary cues like text labels or icons should accompany the color to ensure accessibility for color-blind users. Thoughtful application of this color, considering its luminance and potential impact on diverse users, is key to inclusive design.
