The hex color #2137c5, also known as Persian Blue, presents some accessibility challenges. Its relatively low luminance value means that text rendered in this color may not provide sufficient contrast against a light background, potentially violating WCAG guidelines for text contrast. To improve accessibility, consider using this color for larger graphic elements or pairing it with very light or white backgrounds. Text using this color needs to be carefully reviewed with accessibility contrast tools to ensure compliance, or it should be avoided in favor of lighter or darker blues with higher contrast ratios. This is especially important for users with visual impairments who rely on sufficient contrast to perceive content effectively. Also, avoid using this color as the sole indicator of interactive elements.
