#030618

General Information about #030618

The hex color code #030618 represents a very dark shade of blue, often referred to as Blue Charcoal. It is composed of 1.18% red, 2.35% green, and 9.41% blue. In the RGB color space, it has values of R:3, G:6, and B:24. The color's darkness stems from its extremely low values across all three color channels. This makes it suitable for use as a background color or in situations where a very subtle, dark hue is desired. Colors like #030618 are often used in graphic design and web development to create a sophisticated, muted, or nighttime aesthetic. Because of its low luminance, it is essential to carefully consider the contrast ratio when using this color with text or other elements to ensure accessibility.

The color #030618, also known as Blue Charcoal, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value (very close to black) results in poor contrast against most background colors. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. Text or interactive elements using #030618 on a white or light-colored background would likely fail WCAG's minimum contrast ratio requirements (4.5:1 for normal text and 3:1 for large text). Therefore, it's essential to avoid using this color for text, icons, or important UI elements without careful consideration of contrast. When using #030618, ensure that the background color is sufficiently light to meet accessibility standards, or use a lighter text/element color against the #030618 background. Also, consider providing alternative styling options for users who require higher contrast.
