General Information about Cerulean Blue

The hex color #2F5AB7, also known as Cerulean Blue, presents moderate accessibility challenges. Its contrast ratio against white (#FFFFFF) is approximately 3.7:1, which does not meet the WCAG AA standard of 4.5:1 for normal text. This means that using #2F5AB7 for text on a white background might be difficult for users with moderate visual impairments to read comfortably. To improve accessibility, consider using a lighter background color or a darker shade of blue. When using this color for buttons or interactive elements, ensure sufficient visual cues are present, such as clear borders or changes in color on hover, to aid users with cognitive disabilities. It's also advisable to provide alternative text descriptions for images or icons using this color to support screen reader users.
