The color #1F507A, also known as Chathams Blue, presents some accessibility challenges, particularly when used as a background or text color. Its relatively low luminance value means that it requires careful consideration of contrast ratios. To ensure readability and usability, it's essential to pair it with a light foreground color, such as white or a pale yellow. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using a color contrast checker is highly recommended to verify compliance. Additionally, avoid using this color for essential interactive elements without sufficient contrast, as it can hinder usability for individuals with visual impairments. Providing alternative visual cues, such as icons or underlines, can further enhance accessibility.
