#000618

General Information about #000618

The hex color code #000618 represents a very dark shade of blue, often referred to as Blue Charcoal. It is composed of 0% red, 2.4% green, and 9.4% blue. In the RGB color space, this equates to (0, 6, 24). The color's darkness is due to the low values across all three color channels. Its primary characteristic is its deep, muted tone, which can evoke feelings of sophistication and mystery. Due to the absence of red and very low levels of green and blue, this color appears almost black, thus its classification as a very dark blue. In terms of usage, it is generally used sparingly, and it can be used for backgrounds and subtle accents. The color is generally seen as elegant. To ensure accessibility, careful consideration must be given to contrast ratios.

The color #000618, also known as Blue Charcoal, presents significant accessibility challenges, primarily due to its extremely low luminance. The contrast ratio against standard white (#FFFFFF) is very poor, making text and other elements rendered in this color difficult to perceive for users, especially those with visual impairments. It is crucial to avoid using this color for text or interactive elements without careful consideration of contrast. For instance, using white text on a #000618 background might not meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio, potentially excluding users. To improve accessibility, consider using lighter shades or contrasting colors for foreground elements. Tools are available to check color contrast ratios to ensure compliance with accessibility guidelines, promoting inclusive design practices. Avoid using this color for important information or interactive elements without sufficient contrast.
