About International Klein Blue

International Klein Blue, with the hex code #0029B0, is a deep, vivid blue hue that is known for its intense and captivating presence. This particular shade of blue was developed by the French artist Yves Klein in collaboration with a paint manufacturer, and it was specifically created to capture the intense ultramarine color that Klein admired. It's a color that seeks to encapsulate the purest expression of blue, aiming for a quality that transcends mere color and becomes a sensation. Its unique matte finish further enhances its intensity, absorbing light rather than reflecting it, which contributes to its striking visual impact. Its registration as a trademarked color exemplifies its iconic status in art history.

International Klein Blue (#0029B0) presents a challenge from an accessibility standpoint, particularly when used as text against a white background. Its low luminance creates insufficient contrast, potentially making it difficult for users with visual impairments to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This color, especially when paired with light backgrounds, may not meet these standards, requiring designers to consider alternative color pairings or adjustments. When using this color, it's crucial to test the contrast ratio with accessibility tools to ensure readability for all users. Darker shades or high-contrast backgrounds can significantly improve accessibility. Always prioritize inclusive design by considering the needs of users with varying visual abilities.
