General Information about Blue Charcoal
The hex color #00091b, commonly referred to as Blue Charcoal, is a very dark shade of blue with a hint of gray. It is composed of 0% red, 3.53% green, and 10.59% blue. In the RGB color space, it signifies a muted and deep tone, often associated with sophistication and tranquility. Due to its low brightness and saturation, Blue Charcoal projects a sense of understated elegance, making it suitable for various design applications where a subtle and calming presence is desired. It has a very low perceived luminance, which impacts its accessibility when used in text or user interface elements. The color name 'Blue Charcoal' accurately captures its essence, evoking the image of dark, smoldering charcoal with a subtle bluish tint. This color can be very helpful to create a professional and subtle look.
The hex color #00091b, also known as Blue Charcoal, presents significant accessibility challenges, especially when used as text on a white or light-colored background. Its very low luminance of approximately 0.004 makes it difficult for individuals with visual impairments, including those with low vision or color blindness, to distinguish text or elements using this color. According to WCAG (Web Content Accessibility Guidelines) standards, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. Blue Charcoal is unlikely to meet these standards when paired with lighter backgrounds. Therefore, it's crucial to use this color sparingly and thoughtfully, always ensuring adequate contrast. Consider pairing it with much lighter, contrasting colors to improve readability and overall accessibility for all users. Tools like contrast checkers can assist in verifying compliance with accessibility guidelines.
