About International Klein Blue

International Klein Blue (IKB), represented by the hex code #0514AE, is a deep blue hue known for its intensity and vibrancy. This color was developed by the French artist Yves Klein in collaboration with a paint supplier to achieve a specific ultramarine pigment that would maintain its brilliance when suspended in a synthetic resin. Klein sought to capture the purest expression of blue, associating it with spirituality, the sky, and the infinite. IKB is not just a color; it's an artistic statement and a cultural icon. It is a registered trademark and is often used in art, design, and fashion to evoke a sense of depth, emotion, and visual impact. Its unique formulation and history contribute to its enduring appeal and recognition.

The color #0514AE, also known as International Klein Blue, presents some accessibility challenges, particularly in text and user interface design. Due to its low luminance, it provides insufficient contrast when paired with lighter colors like white or yellow. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #0514AE as a background with light text may not meet these requirements, potentially causing readability issues for users with visual impairments. To enhance accessibility, consider using darker shades of gray or black for text on an #0514AE background or pairing it with a significantly lighter accent color that provides sufficient contrast. Tools like contrast checkers can help evaluate and adjust color combinations for optimal accessibility. Ensuring sufficient contrast is crucial for creating inclusive and user-friendly designs.
