#000319

General Information about #000319

The hex color #000319, often referred to as Blue Charcoal, is a very dark shade of blue. It is composed of 0% red, 1.2% green, and 9.8% blue. In the RGB color space, this equates to R:0, G:3, B:25. The color is more prominent in the blue spectrum. Given its low RGB values, this color is characterized by its minimal brightness and significant darkness. This makes it challenging for use in scenarios where contrast is important, such as text over backgrounds. The color is more suited for applications where a subtle or dark aesthetic is desired and careful consideration is given to complementary colors to provide adequate contrast and visual balance.

The hex color #000319, also known as Blue Charcoal, presents significant accessibility challenges, particularly in text-based contexts. Its extremely low luminance value results in very poor contrast against almost all background colors, including white. According to WCAG guidelines, sufficient contrast is essential for readability, especially for users with visual impairments. Using #000319 for text or interactive elements against a light background will likely fail accessibility checks. To improve accessibility, consider using lighter shades or alternative colors with higher luminance values to ensure adequate contrast. Tools such as contrast checkers can help determine compliance with accessibility standards. It is highly recommended to avoid this color for critical visual elements unless paired with very light or bright complementary colors. Prioritizing accessibility ensures inclusivity and usability for all users.
