Black Rock

#030431

General Information

The hexadecimal color code #030431 represents a very dark shade of blue, often referred to as 'Black Rock'. In the RGB color model, it is composed of 1.18% red, 1.57% green, and 19.22% blue. This translates to a color that is heavily weighted towards the blue end of the spectrum, resulting in its deep, almost black appearance. The color is primarily used in contexts where a dark, sophisticated, or mysterious tone is desired. Due to its low luminance, it can present challenges in terms of accessibility, requiring careful consideration of contrast ratios when used in conjunction with text or other visual elements. Its perceived mood is serious and conservative.

The hex color #030431, also known as Black Rock, presents significant accessibility challenges due to its extremely low luminance. Its very dark nature results in poor contrast against lighter backgrounds, making it difficult for users with visual impairments to discern text or important UI elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Black Rock fails to meet these thresholds with almost any background color other than pure white or very light shades of yellow or cyan. Web developers should avoid using this color for primary text or interactive elements. If it's essential for branding purposes, ensure that sufficient contrast is provided using alternative, lighter colors for foreground elements and interactive components. Careful consideration of color combinations is crucial to ensure readability and usability for all users, including those with low vision or color blindness. Using contrast checking tools is highly recommended to validate accessibility before deployment.
