The color #0B3AA9, also known as International Klein Blue, presents some accessibility challenges. Its dark hue means it generally requires light-colored text for sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using a very light color such as white or a light yellow will help to meet this ratio. It is important to test the color combination with accessibility evaluation tools to ensure readability for users with visual impairments. Also, avoid using this color as the sole indicator of important information such as links or error messages without additional cues, because colorblind users may not be able to distinguish it easily from other colors. Always consider users with different types of color blindness and low vision by providing sufficient contrast and alternative cues, for instance, using labels or icons.
