The hex color #145A6A, also known as Chathams Blue, presents some accessibility considerations for web design. Its relatively low lightness value means that text rendered in this color against a white background may not meet WCAG (Web Content Accessibility Guidelines) contrast requirements. To ensure readability for all users, including those with visual impairments, it's crucial to use a light-colored text on this background or, conversely, a dark background with Chathams Blue text. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Tools such as contrast checkers can help verify compliance. When using this color for interactive elements such as buttons or links, sufficient visual cues beyond color alone should be provided to ensure usability for colorblind users. For example, consider adding text labels, icons, or changes in shape or size upon interaction.
