The hex color #0F3F8C, also known as Congress Blue, presents some accessibility considerations for web development. Due to its relatively dark hue, it's crucial to ensure sufficient contrast when used as either text or a background color. According to WCAG guidelines, 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). When using #0F3F8C for text, pairing it with a very light color like white (#FFFFFF) or a pale yellow would provide adequate contrast. Conversely, if it's used as a background, lighter text colors are essential. Tools like contrast checkers can help verify compliance with accessibility standards. Additionally, avoid relying solely on color to convey important information, as colorblind users may not be able to distinguish it. Consider using supplementary indicators like text labels or icons.
