General Information about #05101A

The hex color code #05101A, often referred to as Blue Charcoal, is a very dark shade of blue. In the RGB color model, it is composed of 2% red, 6.3% green, and 10.2% blue. The color is often associated with feelings of depth, mystery, and sophistication. Due to its very low saturation and brightness, it is considered a neutral color and can be used in various design contexts to create a subtle and calming effect. In terms of color theory, #05101A belongs to the family of dark blues and is closely related to other dark, muted colors. Its hexadecimal representation makes it easily usable in web design, graphic design, and digital art. However, it is important to consider accessibility guidelines when using such a dark color, particularly for text and interactive elements.

The hex color #05101A, also known as Blue Charcoal, presents significant accessibility challenges due to its low luminance. Its dark nature results in very low contrast against common light backgrounds, such as white (#FFFFFF). This severely impacts readability for users, especially those with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for text and interactive elements to be perceivable. Using #05101A for text on a white background would likely fail accessibility standards. To improve accessibility, consider pairing this color with much lighter shades or using it sparingly for decorative elements. A thorough contrast check using online tools is highly recommended to ensure compliance with accessibility requirements and provide a better user experience for everyone, including those with disabilities. Always prioritize clear and legible visual design.
