The color #06379F, a deep smalt, presents significant accessibility challenges. Its low luminance of 5.6 cd/m² falls far short of recommended contrast ratios for readability, especially for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is necessary for normal-sized text and 3:1 for large text. When paired with white (#FFFFFF), the contrast ratio is approximately 3.7:1, insufficient for regular text. To improve accessibility, consider using lighter text colors such as #FFFFFF or #F0F0F0. To ensure readability, increase the font size and weight, or add a background behind the text to improve contrast. Also avoid using it for critical interactive elements or important information without sufficient contrast against surrounding colors. Provide alternative visual cues, such as icons or text labels.
