Cobalt
General Information about Cobalt (#004DB4)
Cobalt, represented by the hexadecimal color code #004DB4, is a deep and vibrant shade of blue. It is commonly associated with qualities such as stability, trust, and intelligence. In the RGB color model, #004DB4 is composed of 0% red, 30.2% green, and 70.6% blue. This color is frequently used in branding and design to convey a sense of professionalism and reliability. Cobalt blue derives its name from the mineral cobalt, which was historically used to create blue pigments in glass and ceramics. Its rich tone makes it suitable for a variety of applications, ranging from corporate logos to artistic creations. In web design, it's essential to consider accessibility when using this color, ensuring sufficient contrast with text and other elements.
The hex color #004DB4, also known as Cobalt, presents several accessibility considerations for web developers. Its relatively low luminance value means that it requires careful attention to contrast ratios, particularly when used for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is necessary for normal-sized text and 3:1 for large text (18pt or 14pt bold) against its background. Using a light color such as white or a very pale yellow for text on a Cobalt background would typically meet accessibility standards. Conversely, darker shades should be avoided as they could result in insufficient contrast, making the content difficult to read for users with visual impairments. Also, consider providing alternative visual cues beyond color alone, such as underlines or icons, to ensure usability for users with color vision deficiencies.
