The color #1E3F66, a deep and muted blue, presents some accessibility challenges, especially when used as a background for text. Due to its low luminance, it requires careful consideration of contrast ratios. For text to be readable against this background, it should be a light color such as white or a very pale yellow to ensure sufficient contrast, ideally meeting WCAG AA standards (a contrast ratio of 4.5:1 for normal text and 3:1 for large text). Using darker text colors like black or dark grays will likely result in illegibility and a poor user experience. When using this color for interactive elements like buttons, ensure sufficient visual cues are provided beyond color alone, such as underlines, borders, or icons, to cater to users with color vision deficiencies. Providing sufficient spacing between elements will also make the design more accessible.
