#191f45 - Konkikyō Blue color

This color is a very deep, cool indigo-blue leaning toward near-black, like the sky moments after sunset. It carries strong blue-violet undertones that read as sophisticated and moody, creating a sense of calm authority. It works well as a background or accent in elegant, restrained palettes, pairing beautifully with warm metallics or crisp whites for high contrast. Use it to evoke night, depth, and quiet refinement in branding, interfaces, or interior schemes where subtle drama is desired.
