The color #0D348B, also known as Smalt, presents some accessibility challenges, especially when used as a text color. Its low lightness value (approximately 14%) means that it requires very light foreground colors to meet WCAG (Web Content Accessibility Guidelines) contrast requirements. For body text, a contrast ratio of at least 4.5:1 is recommended, and for large text (14pt bold or 18pt regular), a ratio of 3:1 is acceptable. When using #0D348B for backgrounds, ensure that all text and interactive elements have sufficient contrast. Tools like the WebAIM Contrast Checker can assist in verifying compliance. Additionally, avoid using this color as the sole indicator for important UI elements, as users with color vision deficiencies may struggle to perceive them. Provide redundant cues, such as text labels or icons, to ensure usability for all users. Considering alternatives with slightly higher lightness or saturation may also improve accessibility without significantly altering the intended aesthetic.
