This hue is inspired by the signature blue LEGO bricks, a color that has been a cornerstone of the toy’s palette since the 1960s. The classic medium blue—bright, balanced, and instantly recognizable—was engineered to maintain consistent tone across decades of plastic production. Made from acrylonitrile butadiene styrene (ABS), LEGO’s blue owes its even saturation and subtle gloss to carefully standardized pigments that resist fading and wear. The shade strikes a perfect middle ground between playfulness and precision, evoking creativity, structure, and endless possibility—hallmarks of the LEGO system itself.
