#0A0D23

General Information about #0A0D23

The hexadecimal color code #0A0D23 represents a very dark shade of blue, often described as ebony. In the RGB color model, it is composed of 3.92% red, 5.1% green, and 13.73% blue. This composition results in a color that is closer to black than pure blue, lending it a sophisticated and mysterious quality. Colors like #0A0D23 are commonly used in design to evoke feelings of depth, seriousness, or luxury. Its dark nature makes it a versatile choice for backgrounds and accents, though careful consideration must be given to contrast when used with text to ensure readability. The color is created by subtractive mixing of cyan, magenta, and yellow, where these colors absorb specific wavelengths of light, resulting in the perceived dark hue. The closer the color gets to black, the more of the red, green and blue lights are absorbed.

The hex color #0A0D23, also known as Ebony, presents significant accessibility challenges due to its extremely low luminance. When used as a foreground color for text, it necessitates a very light background to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Ebony falls far short of these recommendations when paired with moderately dark colors, making it unsuitable for most text applications without careful consideration. Designers should rigorously test color combinations using accessibility tools to prevent visual impairment for users with low vision or color blindness. Using it for purely decorative elements without conveying essential information might be acceptable, but pairing with appropriate contrasting colors is essential for interactive elements.
