General Information about Black Rock (#100A30)

The hex color #100A30, often referred to as "Black Rock", is a deep, dark shade that resides in the realm of muted blues and blacks. It's composed of relatively low RGB values, indicating its darkness and lack of strong chromatic presence. In color theory, #100A30 evokes a sense of sophistication, mystery, and subdued elegance. Its limited saturation and darkness make it suitable for creating backgrounds or accentuating lighter, more vibrant colors. Understanding its properties within the color spectrum allows designers and artists to utilize it effectively in various creative applications, from web design to visual arts. It represents a subtle blend of blue and black, giving a unique visual presence.

The hex color #100A30, also known as Black Rock, presents significant accessibility challenges, especially in web design. Its very dark nature results in low contrast against lighter backgrounds, which is crucial for readability. According to WCAG guidelines, sufficient contrast between text and background is essential for users with visual impairments. Using #100A30 for text or interactive elements without ensuring a high contrast ratio (at least 4.5:1 for normal text and 3:1 for large text) can exclude users with low vision. Therefore, when employing this color, it's vital to pair it with very light shades or adhere to accessibility testing to confirm compliance. Tools like contrast checkers can help ensure adequate contrast levels, promoting inclusive design and a better user experience for all.
