The color #280B85, also known as Blue Gem, presents some accessibility challenges, primarily due to its low luminance. When used as a background color, it requires careful selection of foreground text colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. White or light shades of yellow and green are often good choices for text on this dark blue background to meet these requirements. In situations where visual acuity may be limited, such as for users with impaired vision, careful consideration and testing are paramount. It's not suitable for small text or elements where clarity is critical. Using color alone to convey information should be avoided; instead, supplementary indicators such as labels or icons should be included to ensure usability for all users, including those with color vision deficiencies.
