International Klein Blue

General Information about International Klein Blue

International Klein Blue, often referred to as IKB, is a deep shade of blue first mixed by the French artist Yves Klein. IKB's visual impact comes from its heavy reliance on ultramarine pigment and Klein's technique for maintaining the color's intensity. It's known for its ability to evoke feelings of depth, infinity, and transcendence. Klein patented the color to preserve its uniqueness, making it a distinctive part of his artistic legacy. In the world of color psychology, this particular shade is often associated with knowledge, power, integrity, and seriousness. It's used in various fields, from art and design to branding and marketing, to convey these specific qualities and create a lasting impression.

The hex color #0232ae, also known as International Klein Blue, presents some accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 10 cd/m² means that text rendered in this color against a white background may not meet WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. Specifically, the contrast ratio is around 4.09:1, which falls short of the AA level requirement of 4.5:1 for normal-sized text. To ensure accessibility, it's crucial to use this color judiciously. Pairing it with lighter shades for text or interactive elements is advisable to improve readability and usability for all users, including those with low vision or color blindness. Consider using tools to verify color contrast ratios to ensure compliance with accessibility standards.
