General Information about #090B2C

The hex color code #090B2C, also known as Black Rock, represents a very dark shade of blue-leaning gray. It is composed of 3.53% red, 4.31% green, and 17.25% blue. In the RGB color model, this translates to R:9, G:11, B:44. The corresponding CMYK values are C:79, M:75, Y:0, K:83. This color is typically perceived as somber, serious, and sophisticated. Due to its low luminance value, it is generally more suitable for backgrounds or accents rather than primary text. The hexadecimal system is a base-16 numeral system often used in computing and digital design to represent colors. Each two-digit segment represents the intensity of the red, green, and blue components, respectively.

The hex color #090B2C, also known as Black Rock, presents significant accessibility challenges due to its low luminance. Its dark nature results in very poor contrast against typical light-colored backgrounds, such as white (#FFFFFF). This lack of contrast makes it difficult for individuals with visual impairments, including those with low vision or color blindness, to read text or discern important visual elements. Web developers should avoid using #090B2C for text or interactive elements unless paired with a very light color 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 (Web Content Accessibility Guidelines) standards. Using contrast checking tools can help to verify compliance and ensure a more inclusive user experience. Alternative, lighter colors should be considered to improve accessibility.
