Its low luminance value necessitates careful consideration of contrast ratios when used for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. This dark blue shade will likely require very light text colors, such as white or very pale yellow, to meet these standards.
