Cobalt
General Information about Cobalt
Cobalt, represented by the hexadecimal color code #013AB3, is a deep shade of blue. It belongs to the blue color family. Cobalt is often associated with qualities such as stability, trust, and intelligence. In color psychology, blue is known to evoke feelings of calmness, peace, and security. The name "Cobalt" is derived from the German word "kobold", meaning goblin. Historically, cobalt pigments were used in the production of blue glass and ceramics. Cobalt oxide is used as a pigment to create different shades of blue in many types of paints. Due to its chemical properties, cobalt is often used in batteries.
The color #013AB3, also known as Cobalt, presents some accessibility challenges, particularly in text-based applications. Its low lightness value means that text rendered in this color requires careful consideration of contrast ratios against background colors. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using Cobalt for text, it's crucial to pair it with a very light background, such as white or a very pale yellow, to ensure readability for users with visual impairments. For decorative elements, consider its impact on users with cognitive disabilities or color vision deficiency. Ensure that information is not conveyed solely through color, and provide alternative visual cues or text descriptions where appropriate. Tools like contrast checkers can help evaluate color pairings for optimal accessibility.
