#010C19

General Information

Blue Charcoal, represented by the hexadecimal color code #010C19, is a very dark shade of blue. It is composed of 0.4% red, 4.7% green, and 9.8% blue. In the RGB color space, it has the numerical values (1, 12, 25). This color is often associated with feelings of calmness, sophistication, and mystery. It is not a very common color in nature, which contributes to its unique and elegant appeal. Blue Charcoal belongs to the broader family of blue hues, but its dark nature sets it apart from brighter, more vibrant blues. The darkness of this color is due to the very low values in all three color channels.

The hex color #010C19, also known as Blue Charcoal, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value (very dark) results in poor contrast against most background colors, especially white. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. Text or interactive elements using #010C19 on a white background would likely fail to meet minimum contrast ratio requirements, making it difficult for users to discern content. To improve accessibility, consider pairing #010C19 with significantly lighter colors to ensure adequate contrast. Tools like contrast checkers can help determine if the color combination meets accessibility standards. Additionally, avoid using #010C19 for critical information or calls to action without careful consideration of contrast. Alternative color palettes that offer better contrast should be explored to cater to a wider range of users, including those with low vision or color blindness.
