The color #1E4D70, also known as Chathams Blue, presents moderate accessibility challenges. Its relatively low luminance requires careful consideration when used for text or interactive elements. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. When using this color for text, it's essential to pair it with a light background to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). For graphical elements and user interface components, a contrast ratio of 3:1 is necessary. Tools like contrast checkers can help verify compliance. Additionally, avoid relying solely on color to convey information; use text labels or icons to provide redundancy for users with color vision deficiencies. Proper implementation will ensure your designs are accessible and inclusive.
