Dark Blue
General Information
The hex color #0D0DD9 is a dark shade of blue, often associated with qualities like depth, stability, and authority. In the RGB color model, it is composed of 5.1% red, 5.1% green, and 85.1% blue. This signifies that blue is the dominant component, contributing significantly to its distinctive hue. Because of its high blue value, it is typically associated with feelings of trust and security and may be used in many marketing materials to instill confidence. It is important to note that its perceived attributes and effects are always based on context.
The color #0D0DD9, a deep dark blue, presents significant accessibility challenges, particularly in text-based applications. Its low luminance value means that it requires very light text (white or near-white) to achieve sufficient contrast for readability, especially for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using this dark blue as a background or text color without careful consideration of contrast can exclude users with low vision or color blindness. Designers should prioritize providing alternative color schemes or user-adjustable contrast settings to ensure inclusivity. Tools like contrast checkers are essential for verifying compliance with accessibility standards, preventing potential barriers for a significant portion of users.

Applications
Web Design Accent
In web design, this dark blue can serve as an accent color for backgrounds or headers. It evokes a sense of trust and stability, making it suitable for websites in the finance, technology, or healthcare industries. However, due to its low luminance, it should be used sparingly and always paired with high-contrast text or elements to ensure accessibility. It can effectively highlight key information or create visual interest without overwhelming the user.
Data Visualization
In data visualization, dark blue is used as a primary color, and is effective for representing data sets due to its visibility and distinct contrast with lighter backgrounds. Its association with trustworthiness and precision is also valuable for conveying complex information clearly and accurately. This can be utilized in charts, graphs, and maps to effectively communicate insights and trends to the audience.
Interior Design Accent
In interior design, dark blue can create a sophisticated and calming atmosphere in bedrooms or living spaces. It is commonly used for accent walls, furniture upholstery, or decorative accessories. To prevent the room from feeling too dark, it's important to balance the dark blue with lighter colors, such as white, beige, or light gray, and incorporate ample natural light.
