The color #145087, also known as Chathams Blue, presents some accessibility challenges, particularly concerning color contrast. When using this color for text or interactive elements, it is crucial to ensure sufficient contrast against the background. According to WCAG guidelines, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular) to meet AA compliance. For AAA compliance, these ratios increase to 7:1 and 4.5:1, respectively. Using a color contrast checker tool can help determine whether the color combination meets the minimum contrast requirements. In cases where contrast is insufficient, consider adjusting the color by lightening it or using a darker shade for the background. Additionally, providing alternative visual cues such as underlines or icons can benefit users with low vision or color blindness.
