General Information about Blue Charcoal (#051016)

The hexadecimal color code #051016 represents a very dark shade of blue, often referred to as Blue Charcoal. In the RGB color model, it is composed of 2% red, 6% green, and 9% blue. This results in a deep, muted color with a slight cool undertone. The color is commonly associated with sophistication, depth, and calmness. Due to its low brightness and saturation, it is often used as a background color or in combination with brighter, more vibrant hues to create contrast and visual interest. Its near-black appearance makes it a versatile choice for various design applications where a subtle and understated color palette is desired. The color is more prominent in web design, graphic design and can be used in fashion and interior design.

The hex color #051016, also known as Blue Charcoal, presents significant accessibility challenges, particularly concerning color contrast. When used as a background color, it requires very light text (ideally white or near-white) to ensure readability for users with visual impairments. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. This dark hue often fails to meet these standards with typical text colors, making it unsuitable for large blocks of text or crucial interface elements. Designers must carefully consider color pairings and provide sufficient contrast to meet accessibility requirements, possibly by lightening the color or using a lighter alternative. Failure to do so can exclude users with low vision or color blindness. Testing with accessibility tools is essential.
