About Ultramarine (#121889)

The hexadecimal color code #121889 represents a very dark shade of blue, often referred to as ultramarine. It is composed of 7.1% red, 9.4% green, and 53.7% blue. In the RGB color model, this translates to 18 red, 24 green, and 137 blue. Ultramarine, historically derived from the precious mineral lapis lazuli, has long been prized for its rich, deep hue. In modern usage, it retains its association with sophistication, depth, and a sense of the intellectual. This color is more frequently utilized in digital design and art to impart a sense of depth and trustworthiness.

The color #121889, a deep ultramarine, presents significant accessibility challenges. Its low lightness value (approximately 6%) means it offers very little contrast against common background colors like white. This makes it difficult for users with visual impairments to read text or discern important UI elements rendered in this color. Web developers should avoid using #121889 for text or interactive elements unless paired with a very light color to ensure a contrast ratio that meets WCAG guidelines (at least 4.5:1 for normal text and 3:1 for large text). A lighter tint or shade of the ultramarine, or a completely different color with sufficient contrast, would improve accessibility. Consider using contrast checker tools to verify compliance.
