The hex color #283640, also known as Outer Space, presents some accessibility challenges due to its relatively low lightness value. When used as a background color, it necessitates a light-colored text to ensure sufficient contrast for readability. According to WCAG (Web Content Accessibility Guidelines), the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. Using #283640 with dark text would likely fail these contrast tests, making it difficult for users with visual impairments to read the content. Therefore, it's essential to pair it with a very light color such as white (#FFFFFF) or a light shade of gray to provide adequate contrast and ensure accessibility for all users. Consider using color contrast checkers to verify compliance with accessibility standards before finalizing your color scheme.
