General Information about Persian Blue

Persian Blue, represented by the hexadecimal color code #0F31D7, is a deep and vibrant shade of blue with a rich history. In color theory, it is a tertiary color, lying between blue and violet on the color wheel. It is often associated with royalty, depth, and tranquility. The color’s digital representation indicates that it is composed of relatively little red and green but a significant amount of blue. In web design, its deep hue can be both striking and challenging to use effectively. Due to its intensity, it is most commonly used as an accent color rather than a primary background, as prolonged exposure to such a strong color can cause visual fatigue. Its CMYK values are C:91 M:77 Y:0 K:17.

The hex color #0f31d7, also known as Persian Blue, presents significant accessibility challenges, especially in web design. Its low luminance of 9.4 makes it difficult to ensure sufficient contrast against lighter backgrounds, which is essential 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. This color often falls short of these standards, potentially causing readability issues. To mitigate these problems, designers should carefully pair it with very light colors, test the contrast using accessibility tools, and consider providing alternative color schemes that offer better contrast for users with different visual needs. When using #0f31d7 for text, a very light background, such as white or a very pale yellow, would be necessary. Additionally, providing options for users to adjust the color scheme can greatly improve accessibility.
