#031417

General Information about #031417

The hex color code #031417 represents a very dark shade of blue-grey, often referred to as Blue Charcoal. In the RGB color model, it consists of 3/255 red (1.18%), 20/255 green (7.84%), and 23/255 blue (9.02%). This color sits very close to black on the color spectrum, giving it a muted and understated appearance. Colors similar to this are often used in design when a subtle or neutral tone is desired. Because of its low brightness, it's frequently used as a background color where other colors, typically white or light shades, are placed on top to provide contrast. Its use requires careful consideration of color contrast ratios to meet accessibility standards.

The hex color #031417, also known as Blue Charcoal, presents significant accessibility challenges, particularly for users with visual impairments. Its very low luminance value of 0.007 makes it difficult to read text or distinguish elements against a similarly dark background. According to WCAG guidelines, this color fails all contrast ratio tests for normal text, large text, and graphical elements when paired with black. To ensure accessibility, it's crucial to use #031417 with very light colors like white or a light grey. Even then, careful testing with accessibility tools is essential to confirm sufficient contrast. Avoid using this color for critical interface elements or text that requires easy readability without proper contrast consideration.
