The hex color #10506D, also known as Chathams Blue, presents some accessibility challenges, especially when used as a foreground color on a white or light background. Its relatively low luminance of approximately 0.19 means that the contrast ratio against white (#FFFFFF) is only about 2.8:1. According to WCAG guidelines, this does not meet the minimum contrast ratio of 4.5:1 for normal text or 3:1 for large text (18pt or 14pt bold) to ensure readability for users with visual impairments. To improve accessibility, consider using #10506D with a much lighter background, like #FFFFFF, or pairing it with a significantly lighter color for text. Tools like WebAIM's Contrast Checker can help evaluate color combinations. Also, avoid using #10506D for critical interactive elements unless sufficient contrast is provided to ensure usability for all users, including those with color vision deficiencies.
