The color #2D5BB9, a shade of Cerulean Blue, presents moderate accessibility challenges. Its contrast ratio against pure white (#FFFFFF) is approximately 2.8:1, which falls short of the WCAG's recommended minimum of 4.5:1 for normal text and 3:1 for large text. Therefore, using #2D5BB9 for text on a white background may be difficult for users with visual impairments to read comfortably. To improve accessibility, consider using a lighter background color or a darker text color to increase the contrast ratio. For example, pairing it with a very light grey or off-white background can enhance readability. Alternatively, using a white or very light color for text against the #2D5BB9 background can also provide sufficient contrast. Ensuring adequate contrast is crucial for users with low vision or color blindness, allowing them to perceive the content effectively. When used for interactive elements like buttons or links, it's imperative to provide additional visual cues, such as underlines or borders, to ensure they are easily identifiable.
