International Klein Blue
About Hex Color #111BB9
The hexadecimal color code #111BB9 represents a specific point in the color spectrum, often described as International Klein Blue. Hex color codes are a way to define colors numerically, with each two-digit segment representing the intensity of red, green, and blue (RGB) components, respectively. In #111BB9, '11' signifies a small amount of red, '1B' represents a slightly greater amount of green, and 'B9' indicates a considerable amount of blue, resulting in a deep, vivid blue hue. This color is often associated with depth, stability, and inspiration. Because of its intensity, it should be used with care to not overwhelm the visual field.
The hex color #111BB9, a deep and vibrant blue, presents some accessibility challenges, particularly in text applications. Its low luminance value of approximately 0.1 means that it needs to be paired with very light text colors like white or very pale yellows to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When used as a background, ensure foreground elements meet these contrast requirements. Also, avoid using this color as the sole indicator for interactive elements; supplement with labels, icons, or other visual cues to accommodate users with color vision deficiencies. Consider providing alternative color schemes to allow users to customize the display to suit their individual needs and preferences. Proper attention to contrast and redundant coding ensures that this striking color can be incorporated into designs in an inclusive and accessible manner.

It can also be incorporated into accessories like scarves, handbags, or jewelry to add a pop of color to any outfit. When pairing it with other colors, consider using neutrals like black, white, or gray to let the blue take center stage. For a more adventurous look, combine it with complementary colors like yellow-orange or analogous colors like blue-violet and blue-green.

In interior design, this intense blue is a great accent color. Use it to paint one wall, add a statement rug, or highlight with decorative pillows. It will pop out and give the room character. Given its strong presence, it's best balanced with neutral palettes – think soft grays, whites, and creams to maintain a calming atmosphere. Metals like gold or brass can complement its richness, while natural materials like wood and linen add texture. Thoughtful use ensures that the blue enhances, not overwhelms, the overall aesthetic.
