Legibility

Contrast: is #FFFFF0 accessible?

Black text on it reaches 20.81:1, passing AAA. White text fails at 1.00:1.

WCAG 2 gives the same ratio whichever color is the text; APCA does not, so its Lc changes sign and size with polarity.

Mixing

Mixing #FFFFF0

Pairing check

A near-neutral has no complementary hue to pair with, so tell it apart from neighboring grays by lightness contrast alone.

Harmony

Color harmonies for #FFFFF0

A neutral has no hue to rotate, so every harmony collapses back to the same gray. Pair it with an accent color instead.

Or pair it by lightness: steps of its own scale as text on it, and what each can carry.
