International Klein Blue
General Information
International Klein Blue, or IKB, with the hex code #0e24b5, is a deep, vivid shade of blue. It was developed by the French artist Yves Klein in collaboration with a Parisian paint dealer. Klein patented the color in 1957 to preserve its uniqueness and impact, aiming to capture the purest expression of blue. This particular shade is known for its intense saturation and ultramarine pigment, creating a powerful visual experience. In the RGB color model, #0e24b5 is composed of 5.5% red, 14.1% green, and 71% blue. Its visual properties make it a popular choice for art, design, and branding where a strong, memorable impression is desired. Its perceived depth and brilliance set it apart from more common blue hues.
The hex color #0e24b5, also known as International Klein Blue, presents some accessibility challenges, particularly in web design. Its deep, saturated hue can cause readability issues when used as text against a light background or vice versa. According to WCAG guidelines, sufficient contrast between text and background is crucial for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #0e24b5 for text, it's essential to choose a very light background color, such as white or a very pale yellow, to ensure adequate contrast. Similarly, if #0e24b5 is used as a background color, the text should be a light color. Tools like the WebAIM Contrast Checker can help evaluate contrast ratios and ensure compliance with accessibility standards. Using this color sparingly and thoughtfully can improve the user experience for all users.
