The color #1B213C, also known as Big Stone, presents some accessibility challenges due to its dark nature. When used as a background color, it requires light-colored text to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using #1B213C with dark text would fail these criteria, making it difficult for users, especially those with visual impairments, to read the content. To improve accessibility, consider pairing it with a much lighter color such as #FFFFFF (white) or #F0F0F0 (light gray). Tools like contrast checkers can help verify compliance with accessibility standards. Also, consider that colorblind users might perceive this color differently, and the design should account for those differences by providing alternative cues besides color.
