The color #224E79, also known as Chathams Blue, presents some accessibility challenges, particularly in text-based applications. Its relatively low luminance value of 0.07 means that it offers insufficient contrast against similarly dark colors. According to WCAG guidelines, text and interactive elements should have a contrast ratio of at least 4.5:1 against their background. When using #224E79 for text, it is crucial to pair it with a very light background to ensure readability for users with visual impairments. Using online contrast checkers can help determine if a specific color combination meets accessibility standards. Larger text sizes can tolerate slightly lower contrast ratios (3:1), but it is generally safer to aim for the higher ratio. Moreover, avoid using this color as the sole indicator for interactive elements; provide additional cues, such as underlines or icons, to ensure usability for all users.
