The hex color #28404F, also known as Blue Dianne, presents some accessibility challenges, especially in text applications. Its relatively low luminance of around 7% means that it requires a high contrast ratio when paired with text or other interactive elements to meet WCAG guidelines. For body text, a contrast ratio of at least 4.5:1 is recommended, while for large text, a contrast ratio of 3:1 is acceptable. White text on a #28404F background may meet these requirements, but it is crucial to verify with accessibility testing tools. Darker shades of gray or black may not provide sufficient contrast and should be avoided. When using this color for interactive elements like buttons, ensure sufficient visual cues beyond color alone are provided, such as borders or icons, to aid users with color vision deficiencies.
