The story of this color
Kimono (#728CCB) belongs to the Blue color family.
With moderate saturation and balanced lightness, this muted tone feels sophisticated and understated. Muted hues like this excel in editorial design, professional portfolios, and interior spaces that seek calm refinement.
Blue's scarcity in nature made it a late addition to human color vocabulary—Homer's 'wine-dark sea' notably omits the word blue entirely. The breakthrough came with Egyptian Blue (~2200 BC) and later ultramarine from Afghan lapis lazuli, which Medieval artists hoarded for divine subjects. Synthetic ultramarine (1826) and cobalt blue democratized the color, enabling Impressionists like Monet and Renoir to paint blue-drenched landscapes affordably.
Blue is the most universally liked color and dominates corporate branding (Facebook, LinkedIn, IBM, Samsung). Use it to establish trust, competence, and professionalism.
