Ocean & Coastal

The ocean palette spans a remarkable range. Deep ocean colors, midnight navy (#003153), prussian blue (#003153), dark teal (#006994), communicate depth, mystery, and power. Mid-ocean blues and teals, cobalt (#0047AB), cerulean (#007BA7), classic ocean blue (#006994), feel vivid and energetic, the blue of a sunny postcard sea. Shallow water and tropical colors, aqua (#00FFFF), turquoise (#40E0D0), seafoam (#9FE2BF), feel joyful, refreshing, and tropical. Sand and shoreline colors, warm sand (#C2B280), bleached coral (#E8D5C4), sea glass green (#A8D5B5), provide the warm neutral contrast that makes ocean blues pop.

For most design work, you will want to select from across this spectrum rather than staying entirely in the deep or shallow range. A palette with deep navy, mid-ocean blue, and light seafoam creates more visual depth and versatility than one that uses only vivid turquoise.

Ocean palettes are most at home in: travel and hospitality brands, particularly coastal and marine destinations; wellness and meditation apps where the calming quality of blue-green is actively therapeutic; water-adjacent products (surfing, diving, sailing, swimming); marine conservation and environmental brands; and beauty brands where the "clean" associations of water are a selling point.

For web design, ocean blues pair beautifully with warm sandy neutrals as backgrounds. A warm sand (#F5EFE0) or warm white (#FFFDF7) background with ocean blue accents creates a coastal warmth that works for lifestyle brands without feeling cold or corporate.
