About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #073AAD, is a deep, saturated shade of blue that is often associated with artistry and intellectualism. The color derives its name from the French artist Yves Klein, who patented the process of creating this particular hue in the mid-20th century. Its intense and almost mesmerizing quality has made it a popular choice in various artistic and design applications. The color's spectral data reveals that it reflects primarily blue wavelengths, with minimal contributions from other colors, leading to its perceived purity. In color psychology, blue is often linked to feelings of calmness, trust, and stability. However, the depth of International Klein Blue can also evoke a sense of mystery and contemplation.

The hex color #073AAD, also known as International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value of 0.029 results in very poor contrast against standard white backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability. #073AAD fails to meet these criteria, making text difficult to read and distinguish. To improve accessibility, it's crucial to pair this color with lighter hues that provide sufficient contrast. For instance, using a light yellow or beige for text on an #073AAD background would enhance readability. Also, avoid using #073AAD for crucial UI elements or information displays without proper contrast adjustments to ensure inclusivity and usability for all users.
