Deep Tide

A palette built from the mid-depth ocean — not the surface shimmer, not the abyssal dark, but the zone of rich, saturated blue-green that holds light without releasing it. The colors are deeply saturated at mid-low lightness, giving them weight and authority without becoming oppressive. The teal entry provides the palette's warmth and life; the cerulean and sapphire entries anchor it in cool authority. This palette is unusually versatile for a dark-leaning scheme: it works on both light and dark UI surfaces, reads as premium in editorial contexts, and carries marine-tech, fintech, and luxury brand associations. Best for products where gravitas and sophistication matter more than approachability.

Use this when blue needs weight and depth rather than clarity and openness. The teal-velvet brings warmth so the palette does not read as cold. Pair with near-white (#f8fafb) on light surfaces or deep charcoal (#111827) on dark ones.
