The color #07398F, a deep smalt blue, presents some accessibility challenges. Its low luminance of approximately 4% requires careful consideration when used as text or interactive elements. According to WCAG guidelines, to ensure readability, it demands a contrast ratio of at least 4.5:1 against normal text and 3:1 against large text (14pt bold/18pt regular) or user interface components. Therefore, pairing it with very light colors, such as white (#FFFFFF) or very light grays, is essential to meet accessibility standards. Avoid using it for small text or icons against dark or mid-toned backgrounds, as this can cause eye strain and make content illegible for users with visual impairments. Employing contrast checkers can help verify compliance. For graphical elements, ensure meaningful content is not solely conveyed by color, offering alternative cues like text labels or patterns.
