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. It's renowned for its intense saturation and unique matte finish, achieved by suspending pure ultramarine pigment in a synthetic resin. Klein registered this color as a trademark, solidifying its place in art history. Chemically, it is based on synthetic ultramarine, a pigment derived from sodium aluminosilicate with sulfide. The color evokes feelings of depth, infinity, and the sublime, reflecting Klein's artistic vision. IKB has been widely used in art, fashion, and design, becoming a symbol of modernity and innovation. It is also worth noting that other shades of blue can also be associated to similar themes or emotions.
The hex color #0126c5, also known as International Klein Blue, presents significant accessibility challenges. Its very low luminance of approximately 1% makes it unsuitable as a text color on a white background. The contrast ratio is far below the WCAG guidelines for both normal and large text, meaning users with visual impairments, including those with low vision or color blindness, will struggle to read it. To improve accessibility, consider using a much lighter color for text when using International Klein Blue as a background. White text, for example, could provide sufficient contrast. However, it's best to perform accessibility testing with tools like contrast checkers to ensure compliance with WCAG standards and to accommodate a wider range of user needs. Avoid using this color for critical interface elements like buttons or links without careful consideration of contrast and alternative visual cues.

Applications
Web Design Accent
In web design, International Klein Blue can be used as a bold accent color for backgrounds, buttons, or headings to draw attention to specific elements. Its intense hue creates a strong visual impact, making it suitable for websites aiming to convey creativity and innovation. However, due to its low luminance, it should be used sparingly and with careful consideration of color contrast to ensure readability and accessibility. For example, pairing it with white or a very light yellow text can help achieve sufficient contrast. In UI design, the color can be implemented in charts and graphs to visually enhance data representation.
Fashion Statement
In fashion, International Klein Blue can be used in statement pieces like dresses, coats, or accessories to add a pop of color to an outfit. Its bold and distinctive hue makes it suitable for creating eye-catching and memorable looks. The color can also be used in smaller details such as scarves, bags or shoes to add a touch of elegance and uniqueness. It is commonly paired with neutral colors such as black, white, or grey to create a balanced and sophisticated aesthetic. Moreover, it can be used for athletic wear to create a visually appealing and dynamic design.
Interior Design Accent
In interior design, International Klein Blue can be used as an accent color to create a vibrant and modern space. Consider painting a single wall in this hue to make a statement, or use it in decorative items like pillows, artwork, or rugs to add pops of color. It can work effectively in minimalist design to add a focal point of color to an otherwise neutral space. Be mindful of the amount used as too much can overwhelm a space. The color pairs well with neutral tones such as white, grey, and wood to create a balanced and sophisticated look.
