The color is well suited for creating a professional look with a pop of color.
The color #0A40AA, also known as Cobalt, presents some accessibility challenges, particularly concerning color contrast. When used as text against a white background, it may not meet the WCAG (Web Content Accessibility Guidelines) AA standards for contrast ratio, making it difficult for users with visual impairments to read. Similarly, using white text on a Cobalt background might also fall short of these guidelines. To ensure inclusivity, consider pairing Cobalt with lighter shades like #ADD8E6 (light blue) or #E6E6FA (lavender) for sufficient contrast. Alternatively, darker shades like #000080 (navy) can also be suitable. Always test the color combinations using a color contrast checker to guarantee compliance and optimize readability for all users. Moreover, avoid using Cobalt as the sole indicator of important information, as colorblind users may not be able to distinguish it effectively. Supplement color with text labels, icons, or patterns to ensure equitable access.
