The hex color #18301F, also known as Celtic, presents some accessibility challenges, especially when used for text. Its low luminance value means that it needs to be paired with a very light color to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. Using #18301F for text on a dark background would fail these criteria, potentially causing visual strain for users, particularly those with visual impairments. When using this color, web developers should carefully evaluate the contrast ratio using online tools and choose appropriate foreground colors to meet accessibility standards. It is also advisable to provide alternative color schemes for users who may have difficulty distinguishing certain color combinations.
