#000923

General Information about #000923

The hex color #000923, often referred to as "Blue Charcoal," is a very dark shade of blue. In the RGB color model, it is composed of 0% red, 3.53% green, and 13.73% blue. This composition results in a deep, muted color that leans towards the cooler end of the spectrum. Its primary characteristic is its low luminance, making it appear almost black. Due to its dark nature, #000923 is often used to convey feelings of seriousness, sophistication, and depth. In design, it can serve as a subtle background or accent color, providing a sense of understated elegance. However, its limited brightness necessitates careful consideration of contrast when paired with other colors to ensure readability and accessibility. This color is also known for its great neutrality, so it is fit to be combined with strinking colors and patterns.

The hex color #000923, also known as Blue Charcoal, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value of approximately 0.001 makes it difficult to achieve sufficient contrast against lighter backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #000923 for text or interactive elements requires careful consideration of the background color to ensure readability. Pairing it with very light shades like #FFFFFF or #F0F0F0 can improve contrast, but thorough testing with accessibility tools is essential. It is crucial to provide alternative visual cues, such as underlines or icons, to convey meaning for users who may struggle to distinguish the color effectively. Additionally, consider offering a high-contrast mode option to allow users to customize the color scheme for optimal visibility.
