The hex color #1C487C, also known as Chathams Blue, presents several accessibility considerations for web developers. Its relatively dark hue means that sufficient contrast is crucial when pairing it with text or other interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using a light color like white or a pale yellow for text on a #1C487C background will generally provide adequate contrast. Developers should use tools to measure contrast ratios to ensure compliance. Also, avoid using #1C487C as the sole indicator of interactive elements; supplement it with other visual cues like underlines or icons. Ensuring proper color contrast benefits users with visual impairments, making websites more inclusive and accessible. When using this color for charts, be aware that people with colorblindness may struggle to differentiate it from other colors. Therefore, use patterns and labels to improve clarity.
