International Klein Blue
About International Klein Blue
International Klein Blue (IKB), also known as #0029A3, is a deep, vivid blue hue that was developed by the French artist Yves Klein in collaboration with a Parisian paint dealer. Klein sought to create a blue that captured the essence of the sky and sea. The unique quality of IKB comes from its matte finish, which enhances the color's intensity and luminosity. It is a pure ultramarine pigment that is unbound, allowing the color to maintain its brilliance without the reflective qualities of traditional paints. IKB has become iconic in the art world and is known for its striking, almost ethereal appearance. It continues to inspire artists and designers across various fields.
International Klein Blue (#0029A3) presents some accessibility challenges, particularly concerning color contrast. When using this color for text or interactive elements, it's crucial to ensure sufficient contrast against the background. According to WCAG guidelines, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt). Given its dark hue, pairing it with light colors like white or very light shades of yellow or gray can help meet these requirements. Tools like contrast checkers can assist in verifying compliance. Also, avoid using color as the sole means of conveying information; supplement color cues with text labels or icons to accommodate users with color vision deficiencies. Thoughtful consideration of these factors will make designs more inclusive and user-friendly.
