The color #013FB3, a deep cobalt blue, presents some accessibility challenges, especially concerning text contrast. When used as a background, light text colors like white (#FFFFFF) or very light grays are essential to ensure readability. Conversely, if #013FB3 is used for text, a background of white or a very pale yellow (#FFFFE0) is recommended. Avoid using this color for small text or intricate graphical elements, as its darkness can make them difficult to discern. It is important to use accessibility evaluation tools to verify that the contrast ratio meets WCAG (Web Content Accessibility Guidelines) standards, aiming for a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. Also, provide alternative visual cues beyond color to convey information for users with color vision deficiencies. Ensure interactive elements using this color have clear focus indicators for keyboard navigation.
