#100E2E

General Information

The hex color #100E2E, often referred to as "Black Rock", is a very dark shade of blue-black. In the RGB color model, it consists of 6.27% red, 5.49% green, and 18.04% blue. This composition places it within the cooler spectrum of colors, lending it a sense of depth and sophistication. Colors like #100E2E are frequently used to evoke feelings of calmness, stability, and formality. Given its low luminance, it's best suited for applications where it can be paired with lighter colors to provide sufficient contrast. Its relative rarity compared to pure black gives it a distinctive quality, making it a choice for designers seeking a subtle yet impactful dark hue.

The hex color #100E2E, also known as Black Rock, presents specific accessibility challenges, primarily due to its low luminance. When used as a background color, it necessitates very light text to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This dark color might fail these requirements with moderately dark text colors. Designers should rigorously test color combinations with tools that measure contrast ratios to avoid creating barriers for users with visual impairments. Special attention should be given to users with low vision or color blindness, who may struggle to distinguish elements against such a dark background. Providing alternative high-contrast themes can significantly improve the user experience.
