General Information about #030631

The hexadecimal color code #030631 represents a very dark shade of blue, often described as a deep indigo or near-black. In the RGB color model, it is composed of 1.18% red, 2.35% green, and 19.22% blue. This color has a hue angle of 231.4 degrees, a saturation of 88.52%, and a lightness of 10.2%. The color is also known as Black Rock. It is commonly used to evoke feelings of sophistication, mystery, and depth. Due to its low luminance, #030631 is generally not recommended for use as a primary text color, particularly against light backgrounds, due to accessibility concerns related to contrast. Instead, it is better suited for backgrounds, accents, or graphical elements where its dark hue can add a touch of elegance.

The hex color #030631, also known as Black Rock, presents significant accessibility challenges, particularly in text-based applications. Its extremely low luminance value results in very poor contrast against standard light backgrounds (like white or light yellow). According to WCAG guidelines, this color fails all contrast ratio tests for normal text, large text, and graphical elements when paired with white. To ensure readability and usability for all users, including those with visual impairments, it's crucial to avoid using #030631 for text or interactive elements on light backgrounds. If this color is essential for branding purposes, consider using it sparingly and always pair it with very light shades to create sufficient contrast. Using tools that check color contrast ratios is highly recommended during the design process.
