International Klein Blue
About International Klein Blue
International Klein Blue, often referred to as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein patented this color in 1957, aiming to preserve its unique intensity and purity. The color is achieved by suspending ultramarine pigment in a synthetic resin, maintaining the pigment's vibrant quality without dulling. IKB is known for its strong visual impact and association with concepts such as infinity, spirituality, and the immaterial. Its distinctive character has made it a significant color in art, design, and fashion, often used to evoke a sense of depth and emotion.
The hex color #0025ca, also known as International Klein Blue, presents some accessibility challenges, especially when used as a background or text color. Its dark hue offers sufficient contrast against white text, meeting WCAG AA standards for normal text, but it might fall short for smaller or thinner fonts. When pairing #0025ca with other colors, it's crucial to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold/18pt regular or larger). Lighter shades of yellow, orange, or green can provide good contrast. Avoid pairing it with very dark blues, purples, or greens, as these may result in insufficient contrast and readability issues for users with visual impairments. Tools like contrast checkers can help ensure compliance with accessibility guidelines, promoting inclusive design practices for all users.
