Persian Blue

#1F3AC7

General Information about Persian Blue

The hexadecimal color #1F3AC7, also known as Persian Blue, is a deep, vibrant shade of blue often associated with royalty, sophistication, and tranquility. It's created by mixing red, green, and blue light at specific intensities, with its numerical code representing these intensities in hexadecimal format. This particular shade leans more towards the darker end of the blue spectrum. In color theory, Persian Blue can evoke feelings of calmness and serenity, making it a popular choice in various design applications. However, its low luminance means it should be used carefully in contexts where readability and accessibility are important. It is a strong and elegant color that can add depth and character to many applications if used thoughtfully.

The color #1F3AC7, also known as Persian Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value means that text rendered in this color requires a very light background to ensure sufficient contrast. 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 #1F3AC7 on a dark background would result in a contrast ratio far below these recommendations, making the text difficult or impossible to read for many users. Web developers should carefully evaluate the color combinations and consider using tools to check contrast ratios to comply with accessibility standards and provide an inclusive experience for all users, including those with low vision or color blindness. Avoid using it for critical UI elements without thorough testing. Alternative colors with higher luminance should be considered.
