This color is often associated with stability, trust, and authority, making it a popular choice for branding and design elements related to corporate identity and institutions.

The color #1C497F, also known as Chathams Blue, presents some accessibility challenges, particularly regarding color contrast. When used as a background color, it necessitates light-colored text to ensure readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to comply with WCAG guidelines. Using a color contrast checker is crucial to verify compliance. For users with visual impairments, particularly those with low vision or color blindness, insufficient contrast can make content difficult or impossible to perceive. Therefore, designers and developers should carefully consider the pairing of #1C497F with other colors to maintain accessibility and inclusivity. Providing alternative high-contrast themes or allowing users to customize color schemes can further enhance accessibility.
