General Information About Smalt

The color #0A3991, also known as Smalt, is a deep, saturated blue within the blue color family. It is a dark shade, which gives it a sense of richness and sophistication. Smalt derives its name from the historical pigment made by grinding cobalt glass. This pigment was historically used in paintings, ceramics, and other decorative arts. In modern color systems, #0A3991 is defined by its low red (0A), moderate green (39), and high blue (91) hexadecimal values. Because of its depth, it can evoke feelings of calmness, stability, and authority. It can be effectively used in a wide variety of design contexts, especially when the other factors such as contrast and readability are taken into consideration.

The hex color #0A3991, also known as Smalt, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires very light text to ensure readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) requirements. It is advisable to avoid pairing it with dark or similarly toned colors for text or interactive elements. Using tools like a color contrast checker is highly recommended to test combinations. Also, consider providing alternative visual cues for users who may have color vision deficiencies, such as using icons or text labels in addition to color. Ensuring proper focus indicators for interactive elements is also crucial to maintain accessibility.
