The color #1F5079, also known as Chathams Blue, presents moderate accessibility challenges. Its relatively low luminance can create insufficient contrast against light backgrounds, potentially hindering readability for users with visual impairments. According to WCAG guidelines, contrast ratios should ideally be 4.5:1 for standard text and 3:1 for large text. When using Chathams Blue for text or interactive elements, it is crucial to pair it with a very light color, like white or a pale yellow, to ensure adequate contrast. Tools like contrast checkers can help verify compliance. Conversely, for dark mode designs, consider using a lighter tint of blue to maintain readability. Additionally, avoid using this color alone to convey crucial information; supplement it with text labels or icons to accommodate users with color vision deficiency.
