General Information about Cobalt (#0340B0)

The color #0340B0, commonly known as Cobalt, is a deep shade of blue within the blue color family.

Cobalt blue pigment has a long history, dating back to the 19th century when it was developed as a more stable and less toxic alternative to other blue pigments. Today, it is widely used in various applications, including paints, dyes, and plastics. Cobalt is often associated with feelings of tranquility, stability, and depth. It is a versatile color that can evoke both a sense of calm and a feeling of power, depending on its context and application. In web design, it's essential to consider accessibility when using this color, ensuring sufficient contrast with text and background elements.

The color #0340B0, also known as Cobalt, presents significant accessibility challenges, especially when used as text on a white background. Its low lightness value results in very poor contrast, failing WCAG standards for both normal and large text sizes. This can make content extremely difficult, if not impossible, for users with visual impairments to read. To improve accessibility, consider using #0340B0 sparingly for non-text elements like borders or decorative accents. When using it for text, always ensure a sufficiently light background color is used. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Tools like contrast checkers can assist in determining appropriate color pairings. Alternatively, using a lighter shade of blue or a completely different color palette could provide a more accessible user experience. Prioritizing accessibility ensures that your website or application is usable by everyone, regardless of their visual abilities.
