The hex color #2F3347, also known as Tuna, presents some accessibility challenges, especially when used for text or interactive elements. Its relatively low luminance value of approximately 0.06 makes it difficult to achieve sufficient contrast against lighter backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability for users with visual impairments. When using #2F3347 for text, it's crucial to pair it with a very light background color to meet these contrast requirements. If this is not possible, consider using a lighter shade of gray or another color with higher luminance to ensure that the text is easily readable for everyone. For interactive elements like buttons or links, providing clear visual cues beyond color, such as underlines or borders, is recommended to enhance usability for users with color vision deficiencies.
