The hex color code #004CB3, also known as Cobalt, is a deep, rich shade of blue. It is composed of 0% red, 29.8% green, and 70.2% blue. In the RGB color model, this translates to R:0, G:76, B:179. Cobalt blue is often associated with stability, trust, and authority, making it a popular choice for corporate branding and web design. The color exudes a sense of calmness and dependability, often used in contexts where reliability is paramount. It's a versatile color that can be used both as a primary color to set the overall tone or as an accent color to draw attention to specific elements. Cobalt blue combines well with neutral colors like white, gray, and beige, creating a balanced and harmonious palette.

The color #004CB3, a deep cobalt blue, presents some accessibility challenges, especially when used as a foreground color on a white or light background. Its relatively low luminance contrast requires careful consideration to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #004CB3 for text on a white background may not meet these guidelines, potentially making the text difficult to read. To improve accessibility, consider pairing it with a much lighter color for text or using it for larger graphical elements where legibility is less critical. Also, ensure that interactive elements using this color have sufficient visual cues beyond color alone. Adding borders or text labels can further enhance usability for all users, including those with color vision deficiencies.
