The color #0B43A9, a deep shade of cobalt blue, presents some accessibility challenges. Its dark hue requires careful consideration when used as a foreground color. To ensure readability, it's crucial to pair it with light-colored text, such as white (#FFFFFF) or a very pale yellow. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA standards. Insufficient contrast can make text difficult to read, especially for users with visual impairments. Avoid using this color for essential interactive elements or important information without sufficient contrast. Consider providing alternative color schemes that offer better contrast for users with different visual needs. Additionally, avoid relying solely on color to convey information, as users who are colorblind may not be able to distinguish it. Use icons, text labels, or other visual cues to supplement color-based information.
