Pure white is rare in the physical world. Paper has warmth, ink has weight, and screens that ignore this tend to feel clinical — correct, but cold.
We've been building with a warm paper base and a soft near-black for a while now. The contrast is still strong enough to read cleanly, but the page feels printed rather than rendered. It's a small shift that changes the whole temperature of a design.
Restraint is the trick. One warm neutral, one ink, one accent used sparingly. The discipline is what makes it feel intentional instead of decorated.
