The hex color #1a21cc, also known as Persian Blue, presents some accessibility challenges. Its relatively low luminance makes it difficult to read when used as text on a white background. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. Persian Blue generally fails to meet these ratios on light backgrounds, necessitating careful consideration of color pairings. To improve accessibility, consider using a lighter shade of blue or pairing it with a very light background. When using this color, test its contrast ratio using online tools to ensure sufficient contrast with the background color. Also, avoid using it for essential information if color is the only indicator, as colorblind users may not be able to distinguish it properly.
