#b31b1b - Carnelian color

A rich, vivid crimson — deep, warm red with strong saturation and slightly muted darkness that gives it a dramatic, almost blood-red quality. It reads as bold and passionate, conveying urgency, strength, and warmth while retaining a sophisticated, vintage edge. Ideal for commanding accents, branding that needs intensity, or luxurious touches when paired with muted neutrals and metallics. Its intensity demands balance, working best against creams, charcoals, or warm golds to avoid overpowering a palette.
