About Cobalt (#0643B4)
Cobalt, represented by the hexadecimal color code #0643B4, is a deep shade of blue. It evokes feelings of trust, stability, and intelligence. In color psychology, blue is often associated with calmness and serenity, but darker shades like cobalt can also convey a sense of authority and professionalism. Cobalt gets its name from the mineral cobaltite, which has been used for centuries to produce blue pigments in ceramics and glass. This particular shade of blue is relatively low in luminance, meaning it appears darker to the eye. It is formed by low red and green values and a high value for blue in the RGB model. Its CMYK values are Cyan:95%, Magenta:63%, Yellow:0%, Black:29%.
The color #0643B4, a deep cobalt, presents some accessibility challenges. With a low luminance value, it requires careful consideration when used as a background or text color. When used as a text color, it's crucial to pair it with a light background to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular). Tools like contrast checkers can help verify compliance with WCAG guidelines. Avoid using this color for crucial interactive elements without proper contrast, as it may be difficult for users with visual impairments to perceive them. When used as a background, pair it with contrasting elements that are light in color and easy to distinguish.
