General Information about #01339A (Smalt)

The color #01339A, also known as Smalt, is a dark shade of blue with a rich history. Smalt is a glass-based pigment which contains cobalt. It was historically produced by grinding a potassium glass containing cobalt(II) oxide. The resulting powder was used in various applications, including paints, ceramics, and textiles. In the realm of digital color representation, #01339A is defined by its RGB (Red, Green, Blue) components as follows: Red (1), Green (51), and Blue (154). This translates to very little red and green, and a strong presence of blue, giving it the characteristic deep blue hue. The hexadecimal representation is commonly used in web design and graphic design for specifying colors precisely. Smalt is a color that evokes feelings of trust, authority, and stability, making it a popular choice in branding and design.

The hex color #01339A, also known as Smalt, presents some accessibility challenges, particularly in text-based applications. Its low luminance value necessitates careful consideration of color contrast ratios. When used as a foreground color, it requires a light background to ensure readability and compliance with WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to meet Level AA requirements. For Level AAA compliance, these ratios increase to 7:1 and 4.5:1, respectively. Insufficient contrast can hinder users with visual impairments, including those with low vision or color blindness. Avoid using #01339A for crucial UI elements or interactive components without thoroughly assessing its contrast against the background. Providing alternative styling options or high contrast themes can improve accessibility for all users. Careful selection of font weight and size can also mitigate some of the contrast issues.
