The hex color #2758BF, also known as Cerulean Blue, presents certain accessibility considerations for web design. Its contrast ratio against white (#FFFFFF) is approximately 3.44:1, which does not meet the WCAG AA standard of 4.5:1 for normal text. This means that using #2758BF directly on a white background may not provide sufficient contrast for users with moderate visual impairments. To improve accessibility, consider using a lighter shade of blue or a darker background color to increase the contrast ratio. For larger text (14pt bold or 18pt regular), the color meets the WCAG AA requirement of 3:1. Therefore, it is essential to evaluate the context in which #2758BF is used to ensure readability and usability for all users. Tools like contrast checkers can help determine if the color combination passes accessibility guidelines. For broader accessibility, provide alternative styling options for users who need them.
