General Information about #0B308D
The hexadecimal color #0B308D, also known as Smalt, is a deep, saturated shade of blue. In the RGB color model, it is composed of 4.31% red, 18.82% green, and 55.29% blue. This specific combination gives it a rich, almost navy-like appearance. Smalt derives its name from a ground potassium glass containing cobalt, used as a pigment since the 15th century. Historically, it was valued for its vibrant hue and used extensively in paintings, ceramics, and textile dyeing. In modern applications, #0B308D retains its association with sophistication and depth, making it a popular choice for designs seeking to convey trust and stability. Its relatively low brightness value means it is best paired with lighter colors to ensure visual clarity and contrast.
The color #0B308D, a deep shade of blue, presents some accessibility challenges, particularly when used as a background or text color. Its low luminance value (dark color) means it requires careful consideration of contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, sufficient contrast between text and background is crucial. For normal text (14 points or 18 points bold), a contrast ratio of at least 4.5:1 is recommended, while for large text (18 points or 14 points bold) a contrast ratio of 3:1 is the minimum. Using #0B308D for text on a white background, for instance, would likely fail these contrast tests. Therefore, when using this color, designers should choose a very light color such as white or a light yellow for text to ensure that it meets accessibility standards. Tools like contrast checkers can help to verify compliance with WCAG guidelines and ensure content is accessible to all users.
