General Information about Smalt

The hex color #0B3A90, also known as Smalt, is a deep, saturated blue hue that evokes feelings of calmness, trust, and sophistication. In the RGB color model, it is composed of 4.31% red, 22.75% green, and 56.47% blue. Smalt historically refers to a blue pigment made by grinding cobalt glass, used in paintings, ceramics, and other decorative arts. In modern web design and graphic arts, #0B3A90 can be used to create a sense of depth, stability, and professionalism. Its relatively low brightness value makes it suitable for backgrounds or accents, especially when paired with lighter colors to ensure readability and visual balance. The color is often associated with intelligence, authority, and reliability, making it a popular choice for corporate branding and institutional websites.

The color #0B3A90, also known as Smalt, presents potential accessibility challenges, especially when used as text or interactive elements. Its dark hue results in a low contrast ratio against lighter backgrounds, which can be problematic for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. When using Smalt for text, it is essential to pair it with a very light color, such as white or a pale yellow, to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. For interactive elements like buttons or links, consider using a lighter shade of blue or adding a contrasting border to enhance visibility. Testing with accessibility tools and gathering feedback from users with disabilities is highly recommended to ensure an inclusive design.
