General Information about Cobalt (#0342B0)
The hex color #0342B0, commonly known as Cobalt, is a deep and vibrant shade of blue. It is composed of 1.18% red, 25.88% green, and 69.02% blue. In the RGB color model, it is represented as (3, 66, 176). Cobalt blue has a rich history, having been synthesized in the early 19th century as an alternative to the expensive ultramarine pigment. It has since been widely used in various applications, including fine art, ceramics, and textiles. Chemically, Cobalt blue is a pigment made by sintering cobalt(II) oxide with alumina at high temperatures. This process creates a spinel structure, which gives the pigment its characteristic intense blue color. The color is highly stable and resistant to fading, making it valuable in both artistic and industrial contexts.
The hex color #0342B0, also known as Cobalt, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires light-colored text to ensure readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. This deep blue hue may not provide sufficient contrast with darker shades, making text difficult to read for users with visual impairments. To enhance accessibility, consider using a color contrast checker to verify that the contrast ratio meets accessibility standards. Furthermore, avoid using this color for essential visual elements like links or buttons without proper text labels or sufficient contrast, as users may not be able to distinguish them easily. Providing alternative styling options or a high-contrast mode can also improve the user experience for individuals with disabilities.
