The accessibility of #0049B3 (Cobalt) needs careful consideration. Its dark hue means it requires light text for sufficient contrast, ideally white or a very light shade of yellow or grey. Using dark text on this background would create poor readability, especially for users with visual impairments. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. AAA compliance requires even higher contrast ratios. Tools like contrast checkers can help determine if the color combination meets these standards. When using Cobalt, ensure interactive elements have a clear visual focus indicator to aid keyboard navigation. Consider providing alternative high contrast themes to cater to users with different visual needs, enhancing overall accessibility and usability.
