General Information about Cobalt (#0140B3)

Cobalt blue is widely used in various applications, including web design, graphic design, and even in the manufacturing of certain products. The name 'Cobalt' is derived from the German word 'kobold,' which means goblin, because miners often encountered this ore alongside silver and mistakenly believed it was a mischievous spirit preventing them from extracting the silver. Cobalt as a pigment has a rich history, dating back to ancient civilizations, and continues to be a popular choice in modern times.

The hex color #0140B3, also known as Cobalt, presents some accessibility challenges, especially in text-based applications. Due to its relatively low luminance, using it as a text color against a white or light background can result in poor contrast, making it difficult for users with visual impairments to read. According to WCAG guidelines, sufficient contrast is crucial for readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using Cobalt, it is essential to pair it with a very light color or white for the background to achieve the recommended contrast ratio. Alternatively, using Cobalt as a background color with white or very light text can improve accessibility. Also, consider providing alternative color schemes for users who may have color vision deficiencies. Tools are available to check the contrast ratio between different color combinations to ensure they meet accessibility standards.
