#645a8b - Idol color

A dusky, muted violet leaning toward indigo, this deep lavender carries cool blue-gray undertones that temper its richness. It feels sophisticated and slightly vintage—moody but refined—evoking twilight skies, worn velvet, and softened eggplant. Works well as an accent in interiors and fashion for a luxurious yet understated look, pairing beautifully with cream, warm taupe, muted gold, or charcoal. Its medium-low saturation gives it versatility in branding and design when a calm, elegant presence is desired.
