The color #0A3EAA, a deep cobalt blue, presents some accessibility considerations for web design. When using this color for text, it's crucial to ensure sufficient contrast with the background. A light background is necessary to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using online contrast checkers can help determine if the color combination passes accessibility requirements. Additionally, avoid using color as the sole means of conveying information; supplement it with text or icons to accommodate users with color vision deficiencies. Consider using the color as an accent or highlight rather than for primary text, especially against darker backgrounds, to improve overall usability and inclusivity of the design for all users.
