#15072E

General Information about #15072E

#15072E, often referred to as Black Rock, is a very dark shade of purple tending towards black. In the RGB color model, it's composed of 8.24% red, 2.75% green, and 18.04% blue. Its darkness arises from the low values across all three primary color components. This hex code finds usage in various design contexts where a deep, muted color is desired, for example, in backgrounds, accents, or graphic elements. Understanding its composition helps designers leverage it effectively. It conveys a sense of mystery, sophistication, and depth, making it suitable for projects aiming for a luxurious or edgy aesthetic. The color's perceived darkness means it should be used carefully to avoid overwhelming a design or creating accessibility issues.

The hex color #15072E, also known as Black Rock, presents significant accessibility challenges, especially in web design. Its very low lightness value means that text or interactive elements using this color as a background will require extremely light foreground colors to ensure sufficient contrast. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet WCAG AA standards. When using #15072E, careful consideration should be given to color pairings, opting for colors like white, light yellow, or very pale shades of green or blue to create readable and accessible designs. Providing alternative high-contrast themes or color customization options is also crucial to accommodate users with visual impairments. Ensuring sufficient color contrast is not just a best practice, but a legal requirement in many jurisdictions to provide equal access to information.
