General Information about Smalt

The hex color #023A99, also known as Smalt, is a dark shade of blue with a rich history. Smalt is a historical pigment made from potassium glass colored with cobalt. This pigment was widely used from the 15th to 19th centuries in various applications, including painting, ceramics, and dyeing. Its chemical composition consists primarily of silicon dioxide, potassium oxide, and cobalt(II) oxide, which gives it the characteristic blue hue. In the RGB color model, #023A99 is composed of 0.78% red, 22.75% green, and 60% blue. In the CMYK color model, it is composed of 99% cyan, 62% magenta, 0% yellow, and 40% black. This deep and captivating blue evokes feelings of serenity, depth, and sophistication. It is often associated with trust, loyalty, and intelligence. Its historical significance and unique properties make it a fascinating color for both artistic and scientific exploration.

The color #023A99, also known as Smalt, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value results in poor contrast against light backgrounds, making text and interface elements difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Smalt falls far short of these recommendations when paired with standard white backgrounds. To improve accessibility, consider using Smalt with much lighter colors, ensuring sufficient contrast. Alternatively, providing visual cues or labels alongside the color can aid users in distinguishing elements. Assistive technologies, like screen readers, may not accurately convey information if the color contrast is inadequate. Therefore, it is crucial to prioritize sufficient contrast when incorporating Smalt into designs to create an inclusive user experience.
