About Persian Blue (#1C21CA)

The hex color #1C21CA, commonly known as Persian Blue, is a vibrant and deep shade of blue, characterized by its strong presence and slight hint of purple. It belongs to the blue color family and is often associated with qualities such as depth, stability, and confidence. In color psychology, blue is known to evoke feelings of calmness, trust, and serenity. Persian Blue, with its increased intensity, can also convey a sense of strength and boldness. Its hexadecimal value, #1C21CA, represents the combination of red, green, and blue light that creates this specific hue, making it a distinct and recognizable color in digital design and art.

The color #1C21CA, also known as Persian Blue, presents some accessibility challenges, especially in text-based applications. Its relatively low luminance value means it offers insufficient contrast when paired with standard white backgrounds, potentially causing readability issues 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. #1C21CA falls short of these recommendations when used against white. To improve accessibility, consider using it with lighter shades of yellow, orange, or green. Alternatively, for text, a much lighter tint of blue or a neutral color like white or very light gray would provide better contrast. Careful consideration and testing with accessibility tools are crucial to ensure readability and usability for all users.
