General Information about #013A9A (Smalt)

The hex color #013A9A, known as Smalt, is a deep shade of blue with a rich history. Smalt pigment was originally made by grinding blue cobalt glass and was historically used in paintings, ceramics, and other decorative arts. In modern color terminology, #013A9A represents a dark, cool blue tone. Its RGB values are R:1, G:58, B:154, meaning it has very little red and green, and a significant amount of blue. This color is often associated with feelings of stability, trust, and intelligence. In digital design, it should be used carefully due to its relatively low luminance, which can impact readability if not paired with appropriate contrasting colors. The color can evoke a sense of depth and sophistication when used effectively.

The hex color #013A9A, also known as Smalt, presents specific accessibility challenges, especially in web design. Its low luminance value (dark blue) means it requires careful consideration for contrast ratios. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability, especially for users with visual impairments. When using #013A9A as a background color, opt for very light text colors (e.g., whites or very light yellows) to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Conversely, if #013A9A is used for text, a light background is essential. Tools are available online to check color contrast ratios, and these should be used to confirm accessibility. Avoid using this color for essential UI elements or interactive components unless the contrast is rigorously tested and confirmed to be adequate. Furthermore, consider providing alternative color schemes for users who may have color vision deficiencies.
