Its relative darkness means that the color often needs to be paired with lighter colors to provide sufficient contrast.

The color #303547, also known as Tuna, presents some accessibility challenges, especially when used for text or interactive elements. Its low luminance value results in a low contrast ratio against a white background, making it difficult for users with visual impairments to read or distinguish elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. Tuna falls short of these recommendations. To improve accessibility, consider pairing Tuna with lighter colors or using it for purely decorative purposes. When used for text, ensure a sufficiently contrasting background color. Furthermore, avoid relying solely on color to convey important information, as colorblind users may not be able to perceive the difference. Providing alternative cues, such as text labels or icons, enhances usability for all users.
