#03071E

General Information about #03071E

The hex color #03071E, also known as Blue Charcoal, is a very dark shade of blue. In the RGB color model, it is composed of 1.18% red, 2.75% green, and 11.76% blue. Its darkness stems from the low values across all three primary color channels. This color is often associated with feelings of depth, sophistication, and mystery. It is frequently used in designs aiming to convey a sense of elegance or exclusivity. Due to its muted nature, it serves well as a background color, allowing brighter elements to stand out. However, its very low luminance requires careful consideration of contrast to ensure readability, especially when used for text. The color is frequently found in branding materials of tech companies and luxury brands.

The hex color #03071E, also known as Blue Charcoal, presents significant accessibility challenges, particularly for text and interactive elements. Its extremely low luminance value of approximately 0.002 means that it offers very little contrast against other dark colors. According to WCAG guidelines, sufficient contrast is essential for users with visual impairments to perceive content effectively. To ensure accessibility, it's crucial to pair #03071E with very light colors, aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Using tools to check contrast ratios during design is highly recommended. Avoid using this color for critical information or calls to action unless a highly contrasting foreground color is guaranteed. Considering alternative, lighter shades can often provide a more accessible and user-friendly experience.
