This significant dominance of blue light gives the color its characteristic intense blue appearance. In the RGB (Red, Green, Blue) color model, this translates to values of 12 for red, 33 for green, and 190 for blue.

This color tends to evoke feelings of serenity, trust, and intelligence, making it a popular choice for branding and design. It is considered a cool color, often associated with stability and depth.
The color #0C21BE, a deep Persian Blue, presents some accessibility challenges, particularly in text-based applications. Its low luminance value of approximately 5% means that it requires very light text to meet WCAG (Web Content Accessibility Guidelines) standards for contrast. Specifically, to achieve Level AA compliance (the minimum recommended level), text using this color needs to be at least 4.5:1 contrast ratio against its background for normal text and 3:1 for large text (14pt bold or 18pt regular). For Level AAA compliance, these ratios increase to 7:1 and 4.5:1 respectively. When using this color for interactive elements like buttons or links, be sure to provide additional visual cues beyond color alone, such as underlines, borders, or icons, to ensure that users with color vision deficiencies can perceive the interactive nature of the element. Insufficient contrast can make content illegible for users with low vision or color blindness, creating a barrier to access. Therefore, choose text colors carefully and always test the contrast ratio.

Applications
Web Design and UI/UX
This color is excellent for creating a sense of sophistication and depth in web design. It can be used for headers, navigation bars, or as a background color for sections that require emphasis. In UI/UX, it can serve as a primary color for buttons or icons, especially in applications related to finance, technology, or education. Because of its intensity, it's best paired with neutral colors like white, light gray, or even a muted gold for balance and readability. Always consider contrast ratios, particularly when using this color for text elements. It can also be used in dark mode designs to provide a calming but prominent user experience.
Fashion
In fashion, Persian Blue evokes feelings of royalty and elegance. It can be used for evening gowns, formal wear, or as an accent color in accessories. The rich hue pairs well with metallics like silver and gold, and can also be contrasted with warmer colors such as coral or mustard yellow to create a visually striking outfit. Due to its bold nature, it can also be used in casual wear, such as a statement jacket or a pair of stylish shoes to add a touch of sophistication to a more laid-back outfit. It's a versatile color suitable for all seasons but can shine particularly well in the autumn and winter months.
Interior Design
Persian Blue can be used as an accent color to add a vibrant burst of color. Consider using it for an accent wall in the living room or for throw pillows to elevate your space with a luxurious shade. Because of the saturation, make sure the rest of your interior has a lighter tone to avoid overwhelming your interior with a dark palette. Furthermore, you can also consider using plants to create a balanced contrast.
