Classic mid-ocean blue — rich, full-bodied, and immediately coastal
Bright Sea
#2E96D4
rgb(46, 150, 212)
Open sea in full sun — bright, clear, and energetic
Sea Spray
#7DC3E8
rgb(125, 195, 232)

Pale blue at the wave's edge — soft and background-ready
Tidal Blue traces the complete vertical spectrum of the ocean — from the lightless weight of deep water through the brilliant clarity of the open sea to the pale froth at the shoreline. The five colors are ordered by depth and lightness, each one a precise reading of blue at a different distance from the sky. Together they tell a coherent story about water, light, and the coast that translates seamlessly into digital design.
Deep Tide anchors the palette with a navy so saturated it reads almost black at small sizes — ideal for text on Seafoam Haze backgrounds, or as a dominant dark in interface hero sections. Ocean Blue is the working shade of the palette, versatile enough for buttons, links, and brand expressions that want presence without weight. Bright Sea is where the energy lives: this is the blue that catches the eye first and serves best as a call-to-action or highlight color.

Sea Spray and Seafoam Haze soften the palette toward usability. Seafoam Haze works as an alternative to white for backgrounds in designs that want warmth and color while keeping the reading environment calm. Sea Spray sits between the two registers — warm enough to work as an illustration tone or soft badge color, cool enough to never break the palette's maritime coherence.
Tidal Blue is ideal for travel and tourism brands, nautical or sailing products, water sports and outdoor recreation, coastal real estate, and any digital product where trust and clarity are primary visual goals. The palette also works in corporate settings as a fresh alternative to standard corporate navy-and-white — the presence of Bright Sea and Seafoam Haze prevents the predictable corporate read while the deep values maintain authority.
