General Information about Black Rock (#000633)

The color #000633, also known as Black Rock, is a very dark shade of blue leaning towards black. It belongs to the family of blue colors, but its low saturation and luminance values make it appear almost black to the human eye. In the RGB color model, it consists of 0% red, 2.4% green, and 20% blue. This composition explains its deep, muted appearance. In the context of web design, it is often used to create a sense of sophistication or mystery. However, due to its darkness, it requires careful consideration to ensure accessibility and readability. Its hex code, #000633, is a concise way to represent this specific shade digitally, allowing designers and developers to accurately reproduce it across various platforms and mediums. This color can be considered a tertiary color because it lies between black and a dark blue.

The hex color #000633, also known as Black Rock, presents significant accessibility challenges due to its extremely low luminance. When used as a background color, it requires a very light text color to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. A color like #000633 necessitates a text color close to white to achieve this. Furthermore, it's crucial to consider users with visual impairments who may struggle to differentiate between subtle shades. Therefore, careful consideration and testing with accessibility tools are essential before implementing this color in user interfaces. Using color combinations that offer better contrast ratios is generally recommended for improved accessibility. Also ensure that interactive elements, such as links and buttons, are clearly distinguishable with sufficient visual cues beyond just color. This helps users who rely on other means besides color to understand the content.
