The color #01399A, a deep, saturated blue reminiscent of smalt pigment, presents some accessibility considerations, particularly in web design. When used as a background color, sufficient contrast is crucial for readability. Text color should be chosen carefully; white or very light shades of yellow or green would provide optimal contrast, ensuring users with visual impairments can easily discern the text. Conversely, using darker text colors or colors with similar luminance values should be avoided as it may cause the text to blend into the background, making it difficult to read. In interactive elements such as buttons or links, hover states and focus indicators need high contrast to be perceivable by all users, including those with low vision or color blindness. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text.
