The hexadecimal color code #0047B3, commonly referred to as Cobalt, is a deep, saturated shade of blue. It is composed of 0% red, 27.8% green, and 70.2% blue. In the RGB color space, it signifies a strong presence of blue light, contributing to its cool and calming appearance. Cobalt's popularity stems from its versatility and association with stability, trustworthiness, and intelligence. It is frequently used in branding, web design, and various artistic applications to evoke feelings of confidence and professionalism. Understanding the color composition and properties of #0047B3 allows designers and artists to effectively incorporate it into their projects, leveraging its psychological impact to achieve desired aesthetic and communicative goals.
The hex color #0047B3, also known as Cobalt, presents some accessibility challenges, particularly in text-based contexts. Its relatively low luminance can result in insufficient contrast against light backgrounds, making it difficult for users with visual impairments to read. 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 #0047B3 for text, it's crucial to pair it with a very light color like white (#FFFFFF) or a very pale yellow to ensure adequate contrast. For decorative elements or non-textual elements, the contrast requirements are more relaxed, but it's still important to consider the overall visual experience for all users. Employing tools that check color contrast ratios is highly recommended during the design process. Furthermore, avoid using #0047B3 as the sole indicator for interactive elements like links or buttons; supplement it with other visual cues like underlines or icons to improve usability for users with color blindness.
