#090C2B

General Information about #090C2B

The hex color #090C2B, often referred to as Black Rock, is a deep, dark shade of blue-black. It belongs to the family of very low luminance colors, making it challenging to use effectively in certain design contexts due to contrast issues. In the RGB color model, it is composed of 3.53% red, 4.71% green, and 16.86% blue. Its primary attribute is its darkness, which can evoke feelings of mystery, sophistication, and depth. In the CMYK color model, it consists of approximately 79% cyan, 72% magenta, 0% yellow, and 83% black. This composition highlights its lean towards blue tones with a significant black undertone. Due to its low lightness, it requires careful consideration when used in combination with other colors to ensure readability and visual appeal.

The hex color #090C2B, also known as Black Rock, presents significant accessibility challenges, particularly in web design. Due to its low luminance, using it as a primary text color against a white or light background would result in very poor contrast, making it difficult for users, especially those with visual impairments, to read the content. According to WCAG (Web Content Accessibility Guidelines), a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Black Rock falls far short of these recommendations. Therefore, it's imperative to use it sparingly, perhaps as an accent color or in large graphical elements. When employing #090C2B, ensure that it is paired with a very light color (e.g., #FFFFFF or #E0E0E0) to achieve an acceptable contrast ratio. Tools such as WebAIM's Contrast Checker can be used to verify compliance with accessibility standards. Considering accessibility from the outset is crucial for creating inclusive digital experiences.
