General Information about #031112 (Blue Charcoal)

The hexadecimal color code #031112, also known as Blue Charcoal, represents a very dark shade of cyan-blue. It is composed of 1.18% red, 6.67% green, and 7.06% blue. In the RGB color model, this translates to 3 red, 17 green, and 18 blue. This color is very close to black, leaning slightly towards the blue-green spectrum, giving it a cool, muted tone. Due to its low luminance, it reflects very little light, making it a challenging color for readability and accessibility when used improperly. Careful consideration of contrast is essential when using Blue Charcoal in design applications to ensure legibility and user experience. It evokes feelings of depth, mystery, and sophistication.

The color #031112, also known as Blue Charcoal, presents significant accessibility challenges due to its extremely dark nature. Its low luminance results in very poor contrast against standard white backgrounds, making text and other elements difficult to read for users with visual impairments. To ensure accessibility, it is crucial to use this color sparingly and always pair it with very light foreground colors to achieve a contrast ratio that meets WCAG guidelines (ideally 4.5:1 for normal text and 3:1 for large text). This might involve using shades of white, very light grays, or even pale yellows or greens as text or interactive elements displayed against a #031112 background. Thorough testing with accessibility tools is necessary to confirm compliance and ensure readability for all users, including those with low vision or color blindness. Avoid using this color for critical information or interactive elements without careful consideration of contrast.
