#DEFEFC is a pale, temperate off-white. On the Color Lab it reads clean and engineered, restrained and easy to live with. It holds up as a large surface and is too pale to lead as a primary accent.
Not just a swatch — here's how #DEFEFC works with other colors. Named schemes with #DEFEFC in its natural role, and a note on why the supporting colors balance it.
Light Cyan keeps this Nordic scheme quiet — cool greys and a soft white around it, a muted-blue support and a charcoal anchor.
Light Cyan sets a calm, sun-bleached base here, wrapped in bone and paper off-whites and a soft greige, with a single ink accent for wabi-sabi restraint.
Light Cyan opens this coastal palette with sea-glass and warm sand alongside it, grounded by driftwood grey and a deep-navy anchor.
Light Cyan is the single accent in this high-contrast editorial system — set on near-white paper against near-black ink, with a warm grey and a desaturated tint of Light Cyan carrying the quiet middle.
Light Cyan is the vivid signal in this product UI — on a near-black surface with cool white, a slate grey and a lighter tint of Light Cyan.
How #DEFEFC actually behaves in design work — read from its OKLCH lightness, chroma and hue, not just its raw numbers. Ten signals to help you decide where this color earns its place.
Not a swatch to memorise — a color to build with. Here is #DEFEFC at work across the surfaces designers actually ship.
