General Information about #13072E

#13072E, commonly known as Black Rock, is a dark, muted shade that resides within the realm of deep purples on the color spectrum. Hexadecimal color codes like #13072E are primarily used in web design and digital media to precisely define colors. It is formulated by mixing a low intensity of red (19), a very low intensity of green (7), and a moderate intensity of blue (46). The resulting color evokes feelings of mystery, sophistication, and depth. Black Rock is often associated with elegance and can be used to create a sense of calm and introspection. Its subtle nature makes it versatile for use in various design contexts, although its darkness requires careful consideration of contrast to ensure accessibility and readability. The color name 'Black Rock' suggests a sturdy and grounded feel, reflecting its dark and stable nature.

The hex color #13072E, also known as Black Rock, presents significant accessibility challenges, especially in text-based applications. Its low luminance value of approximately 1.12 cd/m² falls far short of the recommended contrast ratios defined by WCAG guidelines. Specifically, for normal text (AA level), a contrast ratio of at least 4.5:1 against the background is required, and for large text, a ratio of 3:1 is necessary. Given its darkness, #13072E necessitates very light foreground colors to meet these standards. Using it as a background color mandates careful selection of text colors like white or very light yellows to ensure readability for users with visual impairments. Failure to do so can render content inaccessible, particularly for individuals with low vision or color blindness. Therefore, developers should critically assess its usability and consider alternative, more accessible color combinations or enhancements to contrast ratios.
