Dark Blue
General Information
The hexadecimal color code #021DD4 represents a specific point in the blue spectrum of the RGB (Red, Green, Blue) color model. It is composed of 02 parts red, 1D parts green, and D4 parts blue. In terms of additive color mixing, this translates to a very strong presence of blue with only minor amounts of red and green. The color is perceived as a dark, intense blue, often described as a navy or midnight blue due to its low lightness value. Hex color codes are commonly used in web design and digital graphics to precisely specify colors for various elements like backgrounds, text, and borders, ensuring consistency across different displays and devices. The color #021DD4 can evoke feelings of depth, stability, and sophistication, which are often associated with blue hues.
The color #021DD4 presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low lightness value results in very poor contrast against light backgrounds, making text and other elements difficult to read. According to WCAG guidelines, it fails all contrast ratio tests for normal text sizes against white. To improve accessibility, consider using this color sparingly, primarily for decorative purposes rather than conveying essential information. When used for text or interactive elements, pair it with a very light color, ensuring a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Employing tools to check color contrast is essential to guarantee readability and compliance with accessibility standards. Adding a thicker font might help to ensure the best experience for people visiting your website.

Applications
Data Visualization
In data visualization, #021DD4 can represent a specific category or data point on charts and graphs. When combined with contrasting colors for other categories, it provides a visual distinction that enhances clarity. However, its use should be limited to situations where colorblindness is not a major concern, or alternative visual cues (e.g., labels, patterns) should be included to ensure accessibility. Consider adjusting the shade for a wide audience.
Fashion Design
In fashion, #021DD4 can be utilized as a bold and striking color for garments or accessories. As a deep blue tone, it adds a sense of sophistication and confidence. Designers might incorporate it into evening wear or statement pieces, paired with metallic or neutral accents to create eye-catching outfits. Its unique tone can be particularly useful for making a bold personal statement and catch attention.
Web Design Accents
This color works in web design as a heading or accent color. Using it sparingly can help to keep the design attractive without overdoing it with color. When using as the color for website elements, be sure to use lighter fonts to ensure that any potential user can easily read the content that you publish to your website or application.
