The hex color #21363C, also known as Outer Space, presents some accessibility challenges, especially when used for text or interactive elements. Its relatively low lightness value (around 18%) means that it requires careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is needed for normal text and 3:1 for large text against its background to be considered accessible for users with visual impairments. When using #21363C for text, it is crucial to pair it with a light color for the background to ensure sufficient contrast. Tools like contrast checkers can help to evaluate the compliance with accessibility standards. Furthermore, avoid using this color as the sole indicator for interactive elements, as colorblind users might not be able to distinguish them. Always provide additional cues like labels or icons.
