Winter has a very specific light. It is low, soft, and a little blue, and the best winter palettes try to bottle that exact feeling rather than chase it with bright color. This scheme starts with a pale Frost Blue as the dominant tone, the shade you see on a windowpane just before the first snow.
From there I let Silver Grey carry the middle and Snow White open everything up so the room can breathe. These three do most of the quiet work, and they read as one steady cool temperature instead of three separate colors.
The depth comes from green. Evergreen Mist is a soft, foggy support tone, and Deep Pine is the accent that grounds the whole thing, like a single cedar bough against fresh snow. Keep the pine to small doses in 2026 — a door, a built-in, a chair — and let the pale tones lead. That restraint is what makes the palette feel calm rather than cold.
