Its relatively low luminance value can pose challenges regarding color contrast, especially when used as a background color with text. It's crucial to ensure sufficient contrast between text and background to meet WCAG (Web Content Accessibility Guidelines) standards, aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Using tools to check color contrast ratios is highly recommended during design and development phases.

When using this color for interactive elements, ensure sufficient visual cues beyond color alone to convey state changes or functionality, catering to users who may have difficulty distinguishing between colors.
