International Klein Blue
General Information about International Klein Blue
The hex color #0123b3, also known as International Klein Blue or IKB, is a deep, saturated blue color known for its striking intensity. Developed by the French artist Yves Klein in collaboration with a Parisian paint supplier, this particular shade of blue was intended to convey the purest expression of blue, representing the boundless and immaterial aspects of reality. Klein registered IKB as a trademark in 1957, solidifying its status as a unique and recognizable color. In the RGB color model, #0123b3 is composed of 0.4% red, 13.7% green, and 70.2% blue. It is a dark color with a relatively low lightness value. IKB's unique vibrancy makes it popular in art, fashion, and design, where it is used to create a bold and impactful visual statement.
The hex color #0123b3, a deep and vibrant blue reminiscent of International Klein Blue, presents some accessibility challenges, especially when used as a primary color for text or interactive elements. Its low lightness value (around 7%) means that it requires very light text (white or near-white) to achieve sufficient contrast for readability, meeting WCAG standards. Otherwise, users with visual impairments may struggle to distinguish text from the background. When used for backgrounds or larger design elements, consider pairing it with lighter complementary colors like #b2dfff or #ffe6cc to increase overall contrast, ensuring that interactive elements like buttons and links are easily identifiable. It is crucial to use an automated color contrast checker to make sure the contrast ratio is at least 4.5:1 for normal text and 3:1 for large text, adhering to WCAG AA guidelines, and even higher (7:1 and 4.5:1, respectively) for AAA compliance. Also, remember that color should not be the only visual means of conveying information. Using icons, underlines, or patterns can help individuals with color blindness perceive differences.

Web Design Accent
In web design, #0123b3 can be used to create a bold and modern look, particularly for headings, call-to-action buttons, or accent elements. However, it should be used sparingly and balanced with lighter colors to avoid overwhelming the user. Consider using it as a background color for a hero section or a primary color for interactive elements, ensuring sufficient contrast with the text. As a brand color it reflects creativity and innovation.

In fashion, #0123b3 evokes a sense of sophistication and boldness. It can be incorporated into clothing designs, accessories, or even makeup looks. A vibrant blue dress can make a statement, while a subtle blue accessory can add a pop of color to an outfit. The blue can also be used in cosmetic packaging to appeal to an innovative and bold demographic.
Interior Design Accent
In interior design, #0123b3 can be used to create a focal point in a room. A statement wall, a piece of furniture, or even decorative accents can incorporate this color to add depth and visual interest. However, it should be used with caution, as too much of this color can make a space feel overwhelming. When using the color in interior design you communicate a bold confidence that the user exudes.
