Its subtle nature ensures that it does not overwhelm other elements in a design, allowing it to function effectively as a background or accent color.

The hex color #28313D, also known as Outer Space, presents specific accessibility considerations, particularly in web design. Its relatively low lightness value indicates that it's a dark color, which implies that it needs a light foreground color, such as white or a very pale shade of yellow, to ensure sufficient contrast. According to WCAG (Web Content Accessibility Guidelines) standards, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. AAA compliance requires even higher contrast ratios. When using #28313D for text or interactive elements, careful evaluation with accessibility tools is vital to confirm compliance and avoid visual impairments for users, especially those with low vision. For decorative elements, although the contrast requirements are less strict, thoughtful consideration enhances overall usability.
