Ranging from 00 (minimum intensity) to FF (maximum intensity).

The hex color #0021E6, a deep and vibrant blue, presents specific accessibility considerations for web developers. Its high saturation and relatively low luminance can pose challenges for users with visual impairments. When using this color for text, it's crucial to ensure a sufficiently high contrast ratio with the background. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA standards. For WCAG AAA compliance, even higher contrast ratios are required. Avoid pairing this blue with very light colors, as this can cause eye strain. Consider providing alternative color schemes for users who may have difficulty perceiving the intended contrast. Using color alone to convey important information should also be avoided; always include text labels or other visual cues. Testing with accessibility tools and user feedback is crucial to ensure an inclusive design.
