The hex color #2C57BA, also known as Cerulean Blue, presents moderate accessibility challenges. Its contrast ratio against white is approximately 3.8:1, which is below the WCAG's recommended 4.5:1 for normal-sized text. Therefore, using #2C57BA for text on a white background may be difficult for users with visual impairments to read comfortably. To improve accessibility, consider using a lighter shade of blue or a darker background color to increase the contrast. Alternatively, use #2C57BA for larger text elements, where the contrast requirements are less stringent. When used for interactive elements such as buttons or links, ensure sufficient visual cues are provided to indicate the interactive nature of the element, beyond just color. Testing with accessibility evaluation tools and getting feedback from users with disabilities is highly recommended.
