Ivory is an off-white color that resembles ivory, the material out of which the teeth and tusks of animals (such as, notably, the elephant and the walrus) is made. It has a very slight hint of yellow.
Objects carved from ivory (and thus colored ivory) have been prized throughout history. However, now that many of the animals from whose tusks they have been made are becoming endangered, international trading bans have been put on the material ivory.
