The hex color #294BB9, also known as Cerulean Blue, presents some accessibility considerations for web development. Its relatively low luminance value means that careful attention must be paid to color contrast, especially when used for text or interactive elements. According to WCAG guidelines, sufficient contrast between foreground and background colors is crucial for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text and graphical components. When using #294BB9 as a background, light text colors like white or light yellow may provide adequate contrast. Conversely, if used for text, a dark background is essential. Tools like contrast checkers can help developers evaluate the compliance of their color schemes. Furthermore, avoid relying solely on color to convey information, as this can exclude colorblind users. Supplement color cues with text labels, icons, or patterns to ensure inclusivity.
