Dark Blue
General Information about #0306B0
The hex color #0306B0, also known as Dark Blue, is a deep, saturated shade of blue within the blue color family. It's represented by 03 for Red, 06 for Green, and B0 for Blue in the hexadecimal system. This translates to very low red and green components and a high blue component, creating its characteristic dark blue appearance. Colors like this are often associated with traits like stability, trust, and knowledge. In color theory, dark blue shades can evoke feelings of calmness and order, and they are often used in professional contexts to convey a sense of authority. Because of its dark nature, it is considered a cool color.
The hex color #0306B0, a dark blue, presents significant accessibility challenges, especially in web design. Its low luminance value means text rendered in this color requires a very light background to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using #0306B0 on a dark or even moderately colored background would likely fail these criteria, making content inaccessible to users with visual impairments. Therefore, careful consideration and testing are crucial to ensure compliance and usability. Tools like contrast checkers can assist in verifying adequate contrast ratios. It's essential to prioritize inclusive design practices and provide alternative color schemes or adjustable settings to cater to diverse user needs.

Applications
Data Visualization
In data visualization, #0306B0 can be employed to represent distinct categories or highlight specific data points, especially when used sparingly against a lighter backdrop. Its deep hue can effectively draw attention to key information within charts, graphs, and infographics. However, due to its limited visibility on dark backgrounds, it should be paired with contrasting colors and clear labels to ensure clarity and accessibility for all viewers. Consider using it to represent the most important data series in a graph.
Branding and Logo Design
#0306B0 finds applications in branding and logo design, where its dark and serious tone can convey a sense of professionalism, trustworthiness, and stability. It is often seen in the logos of financial institutions, technology companies, and organizations seeking to project an image of authority. To maximize its impact, it's essential to consider its use within a broader brand palette and ensure that it harmonizes effectively with other colors. Also, avoid using it in logos if your target demographic are younger people.
User Interface Design
In user interface (UI) design, #0306B0 can be utilized as an accent color for buttons, icons, and other interactive elements to guide user attention and enhance the overall visual hierarchy. However, care must be taken to ensure sufficient contrast between these elements and the surrounding background to comply with accessibility standards. Thoughtful application of this color can contribute to a visually appealing and user-friendly interface. Consider using it as a color when a user has completed an action.
