International Klein Blue
About International Klein Blue
The hex color #0020C0, also known as International Klein Blue (IKB), is a deep and saturated shade of blue. It was developed by the French artist Yves Klein in collaboration with a Parisian paint dealer, Edouard Adam, specifically for Klein's use in his monochrome paintings. The color is renowned for its striking intensity and was officially patented by Klein in 1957. Chemically, IKB is a synthetic ultramarine pigment, which contributes to its unique brightness and matte finish. In the RGB color model, #0020C0 is composed of 0% red, 12.5% green, and 75.3% blue. Its visual impact stems from the strong dominance of the blue component, creating a visually arresting and memorable hue.
The hex color #0020c0, a deep and vibrant blue often associated with International Klein Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability, ideally achieving a contrast ratio of at least 4.5:1 as recommended by WCAG guidelines for normal-sized text. If used for text itself, the background needs to be equally light. Due to its high saturation and relatively low lightness, it's generally not suitable for large blocks of text. When using this color for interactive elements like buttons or links, ensure there's a clear visual cue beyond color alone, such as an underline or a distinct shape change on hover, to support users with color vision deficiencies. Careful consideration is needed to meet accessibility standards and provide a positive user experience for everyone.

Its boldness draws the user's attention, making it effective for guiding user flow. However, due to accessibility concerns, it should be paired with light text and used sparingly. Consider using it for headings or decorative accents rather than extensive backgrounds. It can also be used to create a strong visual identity associated with trust and authority, fitting for financial or educational websites.
Interior Design Accent
In interior design, International Klein Blue (#0020C0) can serve as a striking accent color. It can be used on a feature wall to create a focal point in a room, or incorporated through statement furniture pieces like a vibrant sofa or armchairs. When using such a bold color, it's important to balance it with neutral tones such as white, gray, or beige to prevent the space from feeling overwhelming. The rich blue can add a sense of luxury and sophistication when used in smaller doses, such as decorative pillows or artwork.
Fashion Statement
In fashion, #0020C0 can be used in formal wear to convey confidence and creativity. The rich and intense colour is sure to turn heads. It is best used as a stand-out item against a neutral background.
