General Information about #030331

The hex color code #030331 represents a very dark shade of blue, often referred to as 'Black Rock'. It belongs to the blue color family, but its high concentration of black pigment results in a hue that is almost indistinguishable from pure black. In the RGB color model, #030331 is composed of 1.2% red, 1.2% green, and 19.2% blue. This means that blue is the dominant color component, although it is significantly subdued. In the CMYK color model, which is used for printing, #030331 consists of 94% cyan, 94% magenta, 0% yellow, and 81% black. This indicates that a substantial amount of cyan and magenta inks are needed to reproduce this color accurately on printed materials. The color is not part of the web-safe color palette.

The hex color #030331, also known as Black Rock, presents significant accessibility challenges, especially in web design. Its extremely low luminance (very close to zero) means that text or other elements using this color as a background will require very light foreground colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using a very dark color like #030331 necessitates careful selection of foreground colors, such as white or very light shades of yellow or cyan, to meet these contrast requirements. Without adequate contrast, users with visual impairments, including those with low vision or color blindness, may struggle to read the content. Therefore, when incorporating #030331 into designs, thorough contrast checks are crucial to ensure accessibility for all users. Also avoid using it for essential UI elements.
