The hex color #154C86, also known as Chathams Blue, presents some accessibility challenges, particularly when used as a text color against a white background. Its relatively low luminance can result in insufficient contrast, making it difficult for users with visual impairments to read the text comfortably. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #154C86 for text, it's crucial to ensure that the background color provides adequate contrast. Consider using a lighter shade of blue or a completely different color to improve readability. For decorative elements, the contrast requirements are less stringent, but it's still good practice to aim for sufficient contrast to ensure that the visual design is accessible to all users. Tools like contrast checkers can help you assess and adjust color combinations to meet accessibility standards.
