The color #2A5DBC, a shade of Cerulean Blue, presents some accessibility considerations for web developers. Its contrast ratio with pure white (#FFFFFF) is relatively low, potentially failing WCAG standards for text legibility, especially for smaller font sizes. Using this color for text on a white background might require increasing the font size significantly or using a bolder font weight to ensure readability for users with visual impairments. Conversely, when used on a pure black background (#000000), the contrast improves, but careful evaluation is still necessary. Developers should utilize contrast checking tools to verify compliance with accessibility guidelines. Consider pairing #2A5DBC with lighter shades of yellow, beige, or white to enhance contrast and make content more accessible. Furthermore, provide alternative cues such as icons or text labels to convey information, instead of relying solely on color.
