Cobalt
General Information
Cobalt, designated by the hex code #004BB0, is a deep, vibrant shade of blue. It derives its name from the element cobalt, which is used in pigments to produce this specific hue. In the RGB color model, Cobalt consists of 0% red, 29.4% green, and 69% blue. This composition gives it a strong blue dominance, characterized by its slightly subdued yet intense appearance. Cobalt blue has been historically significant in art and design, known for its stability and brilliance. It is often associated with qualities of trust, stability, and authority, making it a popular choice for branding and design across various industries.
The hex color #004BB0, also known as Cobalt, presents some accessibility considerations for web developers. Its relatively low luminance value means it requires careful pairing with text and background colors to ensure sufficient contrast for readability, especially for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. Using a light color like white or a very pale yellow for text on a Cobalt background can help meet these requirements. It is crucial to test color combinations using accessibility evaluation tools to guarantee compliance and provide an inclusive user experience. Additionally, providing alternative visual cues, such as icons or text labels, alongside color coding can further enhance accessibility for all users.
